RB Leipzig head coach Julian Nagelsmann insisted his side must "stay on the gas pedal" despite closing within two points of Bundesliga leaders Bayern Munich.

Leipzig defeated Hertha Berlin 2-0 on the road on Sunday, capitalising on leaders Bayern's 2-1 loss to Eintracht Frankfurt on Saturday.

Bayern also dropped points last week following their return from the Club World Cup in Qatar, drawing 3-3 with Arminia Bielefeld, meaning the margin at the top has been cut from seven to two points within a week, offering renewed title hope for Naglesmann's side.

However, the 33-year-old German maintained the hard work has only just begun for Leipzig, who have finished the past two Bundesliga seasons in third position.

"It's nice to get closer [to Bayern]," Nagelsmann said. "It used to be a seven-point-gap at one point. My team's reaction impressed me a lot… We have to remain focused and try winning our games.

"I think I said at the beginning of the season that February and March will become harder for the teams, as the impact of the Corona pandemic needs to be overcome in the right way.

"There are a lot of games and we need to stay on the gas pedal, and we did that in today's 90 minutes, as we did in the previous Bundesliga games.

"A lot of good teams are coming up now, with [Borussia Monchengladbach] Gladbach on the weekend, which will be a challenge. But we want to keep being successful in the Bundesliga and winning the games should speak for us."

Napoli forward Victor Osimhen underwent tests in hospital on Sunday after being carried off on a stretcher following a blow to the head in the team's 4-2 Serie A loss to Atalanta.

Osimhen collided with Atalanta's Cristian Romero and fell to the ground in the closing moments of the game, with reports in Italy saying he then lost consciousness on the pitch.

Former Lille star and Nigeria international Osimhen was taken away by ambulance and was due to spend the night in a Bergamo hospital.

Napoli said only the 22-year-old had suffered "head trauma" that necessitated tests to determine whether there was any damage.

In a statement, Napoli said: "The player will remain in Bergamo until tomorrow [Monday] under the clinical observation of the [Napoli] health manager Raffaele Canonico."

Osimhen became Napoli's record signing when he arrived from Ligue 1 outfit Lille last July, joining in a €70million deal.

Marco Verratti acknowledged Paris Saint-Germain are "starting to lose a lot of opportunities" to retain the Ligue 1 title after their 2-0 home defeat to Monaco.

Five days after their thrilling 4-1 victory over Barcelona in the Champions League, PSG crashed to a damaging loss at the Parc des Princes on Sunday.

The defeat is the second of Mauricio Pochettino's tenure and leaves PSG third in Ligue 1, two points ahead of Monaco, in fourth, and four behind leaders Lille.

It means PSG remain winless in their four games against the other sides currently in Ligue 1's top-four positions this season, losing 3-2 and 2-0 to Monaco, 1-0 at home to Lyon and drawing 0-0 at Lille.

Verratti, outstanding against Barca, came on as a 55th-minute substitute in Paris, going on to attempt 43 passes – with an accuracy of 81.4 per cent – and create one chance.

"It was a difficult match; they have very good players, we knew it. It's the kind of match you have to win," Verratti told Canal+. "We are starting to lose a lot of opportunities for the title.

"We concede a goal after five minutes, that can't happen. We have to understand that there are great teams in France.

"We must always play as a team; no one gives us gifts, the other teams are playing the game of their lives against us.

"You have to rise to the occasion, deserve it, play 100 per cent, because otherwise you won't win."

After scoring a hat-trick against Barca, Kylian Mbappe turned in a disappointing performance against his former club.

Since he joined PSG in 2017, Mbappe has scored seven goals against Monaco in Ligue 1; he has only found the net more often against Dijon (nine) in the top-flight during that period.

However, he failed to shine on Sunday. The 22-year-old did not register an attempt on goal and created just one chance.

Pochettino refused to pin the defeat on Mbappe, though.

"In football there are many situations, different opponents, different circumstances," Pochettino told a news conference.

"Football is not mathematical. We weren't at the level today to win at the collective level, not just Kylian. If we have to find a responsible, it's me."

Paris Saint-Germain crashed back to earth with a bump after their Champions League heroics as they suffered a 2-0 Ligue 1 defeat to Monaco on Sunday.

Mauricio Pochettino's side claimed a stunning 4-1 win over Barcelona in the first leg of their last-16 tie on Tuesday, but they never looked like scaling those heights as they slumped to a sixth league defeat of the season.

Sofiane Diop's sixth goal of the campaign handed Monaco an early lead before Guillermo Maripan put the game beyond the hosts' reach shortly after the interval.

The result means third-placed PSG are four points behind leaders Lille, who beat Lorient 4-1 earlier in the day, with Niko Kovac's Monaco two points back in fourth.

Monaco went ahead after just six minutes, Diop heading past Keylor Navas from six yards after Kevin Volland nodded Ruben Aguilar's cross into his path.

That did little to spark PSG into life, and the home team struggled to carve out any clear opportunities in the first half.

The closest they came was when Idrissa Gueye's powerful drive from distance flashed past Benjamin Lecomte's right-hand post.

Things did not get any better for PSG after the interval as Maripan dispossessed Ander Herrera in the penalty area before slotting a fine finish past Navas from 15 yards to double Monaco's advantage in the 51st minute.

Volland inexplicably headed wide from four yards soon after, but it mattered little in the end as Monaco held on to stretch their unbeaten run in Ligue 1 to 11 games.

What does it mean? PSG slump against top-four opposition... again

The swashbuckling side that demolished Barca in midweek was nowhere to be seen at the Parc des Princes as PSG - who managed just one shot on target - suffered a first home defeat in Ligue 1 since Lyon triumphed in the capital on December 13.

Indeed, the defending champions are now winless in their four games against the other sides in the league's top four positions this season. That does not bode well for Pochettino's chances of sealing his first title win as head coach.

Aguilar epitomises Monaco display

Aguilar was at the heart of everything good about Monaco’s fine win. His cross led to Diop’s opener – one of a team-high two key passes – while he made three clearances and three interceptions.

Herrera well off the pace

The former Manchester United midfielder endured a game to forget and it was little surprise to see him hauled off before the hour mark. He was at fault for Monaco's second goal and failed to register a single shot or key pass during his time on the pitch.

What's next?

PSG will hope to return to winning ways when they visit Dijon on Saturday, while Monaco host Brest a day later.

Antonio Conte felt Inter produced an "extraordinary performance" in the 3-0 defeat of Milan, picking out midfield duo Christian Eriksen and Ivan Perisic for special praise. 

The Nerazzurri moved four points clear at the top of Serie A thanks to a resounding triumph in the derby on Sunday, Lautaro Martinez scoring in each half at San Siro. 

Romelu Lukaku struck his 17th league goal of the season to complete the emphatic victory, in the process becoming the first player to score in four successive derbies for Inter since 1950. 

For Conte, it was a case of the best-laid plans coming to fruition, albeit they needed captain Samir Handanovic to make a trio of superb saves early in the second half when the score was still at 1-0. 

"Compliments to our guys, who made an extraordinary performance," Conte said. 

"A very well-prepared match, which they followed perfectly, translating the situations they experienced on the pitch.   

"There is satisfaction in seeing the growth of the group and I am happy because the guys they deserve to reap the benefits of the work we are doing."

Both Eriksen and Perisic, two players linked with moves away in the previous transfer window, enjoyed pivotal roles for Inter.

Making just his seventh league start of the campaign, Eriksen completed 90 per cent of his attempted passes and made nine crosses despite playing in a cental position.

Perisic, meanwhile, provided two assists, including a low cross from Inter's left flank that allowed Martinez to crucially double the advantage not long after a heavy spell of Milan pressure.

"I think the task of a coach is to try to bring all the elements of the squad to improve and to enter into the idea of football that we intend to develop," Conte said when asked about the turnaround in fortunes for the duo.

"The growth of Christian and Ivan, but of all our players, makes me proud."

On Eriksen, who scored a dramatic winner against Milan in the Coppa Italia earlier in the season, the former Chelsea boss added: "Many times hasty judgments are made, as happened for Christian.

"Sometimes it takes a little time, especially when you come from abroad.  

"The same goes for Ivan, who this year has shown a great desire to challenge himself. He put himself at the full disposal of the cause and today he played an extraordinary match. He has incredible potential and must believe even more in himself."

Inter handed Milan a fifth defeat in 2021 in all competitions, which is two more than they suffered throughout the previous year. 

RB Leipzig believe they are now in a Bundesliga title "duel" with Bayern Munich after closing the gap to two points with another win, this time at Hertha Berlin. 

With a draw at home to Arminia Bielefeld and then defeat at Eintracht Frankfurt, Bayern have dropped five points this week since returning from the Club World Cup in Qatar. 

Those setbacks granted Leipzig an opportunity to re-enter a title race that had looked to be over - and Julian Nagelsmann's side capitalised with a 3-0 success at Hertha on Sunday. 

Leipzig have won all five of their Bundesliga away games against Hertha, although they only pulled clear of their hosts in the closing stages. 

Marcel Sabitzer's sublime long-range strike was all that separated the sides until the 71st minute when Nordi Mukiele added a second. 

Sabitzer and Mukiele had each committed errors leading to goals in the midweek Champions League defeat to Liverpool. 

There was then a clinching third courtesy of Willi Orban, moving Leipzig five points ahead of third-placed Wolfsburg while piling the pressure on Bayern. 

Sabitzer, who has 12 career Bundesliga goals from outside the area, albeit this was his first of 2020-21, told Sky Sport: "It was not to be expected that Bayern would drop five points.

"Now we have caught up the points, now there are only two. We are a bit clear of third place, so it's a duel. 

"It doesn't help to talk about it, we have to do it and stick with it week after week. Otherwise I can say something completely different next week and then everyone will laugh at me again." 

Nagelsmann added: "Of course, we're pleased to have moved back to within two points of Bayern. 

"Some teams behind us also picked up points, which makes the victory today even more important." 

Bayern, who have already lost twice in the Bundesliga in 2021 after a sole defeat last year, visit Leipzig on April 3.

Ronald Koeman described Barcelona's failure to beat Cadiz as more disappointing than their Champions League humiliation at the hands of Paris Saint-Germain.

Barca followed up their 4-1 home defeat to PSG in the last 16 first-leg clash on Tuesday with a 1-1 draw in LaLiga against relegation-threatened Cadiz.

Lionel Messi marked his record 506th LaLiga game for the club with a 32nd-minute penalty, but Alex Fernandez levelled from the spot late on after Clement Lenglet was adjudged to have fouled Ruben Sobrino.

The draw meant Barca missed the chance to pull within six points of league leaders Atletico Madrid, who were beaten at home by Levante on Saturday.

"It is disappointing," Koeman said. "These types of games have to be won and we did not.

"It was a great opportunity lost after the loss of Atletico. I am very disappointed, more so than on Tuesday.

"We could not afford to let two points get away. I don't like to blame individual players but we were not up to the task offensively and we have to defend differently. For our quality, we had to win.

"The lead was very narrow and they could equalise at any time, which is what happened. You leave the door open for them to draw at the end if you don't kill the game and score the second.

"It was difficult for us to create opportunities because they were behind the ball and there was no space. We lacked freshness in attack."

Barcelona have failed to keep a clean sheet in eight successive games across all competitions for the first time since 2015.

Despite their issues at the back and the eight-point gap to the summit, Koeman is not giving up hope of Barca posing a serious challenge to Atletico.

"We can still do something," he added. "There is no team that wins games easily.

"But we must recognise that opportunities like this cannot be missed anymore. I don't think it is unforgivable, but it was an opportunity to close the gap.

"[The league] is not more complicated than before. No team is unbeatable, nor are they going to win every game. There are still options. But we have dropped two important points."

Stefano Pioli says Milan are no longer happy simply playing the part of challengers in the Serie A title race and will work hard to recover from a testing stretch that now includes a derby defeat to Inter.

The Rossoneri have led the league for much of the season but slipped four points off the pace with Sunday's 3-0 home loss to their rivals at San Siro.

Lautaro Martinez added to his early opener with a second after the break, with Romelu Lukaku capping Milan's second consecutive Serie A defeat.

Pioli's side also conceded a last-ditch equaliser to Red Star Belgrade in the Europa League since losing at Spezia, their overwhelmingly positive campaign threatening to come off the rails.

Milan have now suffered four defeats in Serie A in 2021, twice as many as in the whole of the previous calendar year.

Pioli saw improvement in this performance compared to the Spezia setback, though, as Milan enjoyed 59.9 per cent of the possession and had 15 attempts, and the coach is determined to stay level-headed.

But the team's ambitions have changed over the course of the campaign and there must now be a response, he added.

"I believe that our strength has always been balance – and belief in our work," Pioli told DAZN.

"If they had told us months ago that at this point of the season we were second in the standings, we would have jumped for joy. This doesn't have to make us happy and content now.

"In these past two or three games, we have not been able to put our quality on the field. We need to get back to doing more.

"We were really poor in the Spezia game. Today we feel sorry for ourselves, for the fans, for the club, but today we played our game.

"We have to maintain clarity, positivity, and evaluate things well. When you lose, you have to work harder and this we will have to do."

While Milan goalkeeper Gianluigi Donnarumma became the youngest player to clock up 200 games in Serie A in the three-points-per-win era, his opposite number ensured the milestone passed with little cause for celebration.

The outstanding Samir Handanovic made eight saves, his most in a game for Inter since pulling off eight against Lazio in January 2019 and most in a Serie A outing since the same number against Juventus in December 2017.

Only three times in Handanovic's Nerazzurri career has he made more than eight stops in a match.

The keeper denied Zlatan Ibrahimovic on five occasions as the veteran Milan superstar failed to add to his tally of 10 Milan derby goals.

Pioli recognised Handanovic's display but refused to criticise Ibrahimovic, who was withdrawn after 75 minutes with cramp in his calf.

"A centre-forward is conditioned by the performance of the team," he said. "In the first half, we did not have the accuracy in the plays, in the final pass.

"In the second half, then we created and had scoring chances. It is a long time since Samir Handanovic saved so often and so well. It is a difficult week, but we will recover."

Just one of Handanovic's saves came in the first half and Pioli rued Milan's slow start as he reflected on the match as a whole.

"The goal immediately after five minutes weighed heavily," he said. "We struggled to find the rhythm, intensity and quality that was needed to find spaces.

"We let Inter play the game where they are strongest.

"In the second half, we were succeeding but we were unable to score in our best moment. Then came the second goal.

"I have nothing to say about the second half of my team; in the first half, we had to do something more."

Lautaro Martinez declared Inter showed their true colours in Sunday's 3-0 derby victory over Milan at San Siro.

The Nerazzurri moved four points clear at the top of Serie A thanks to a double from Martinez and Romelu Lukaku's 23rd goal of the season in all competitions.

Lukaku crossed for his strike partner to nod in after only five minutes and each of them scored after the interval to put the game beyond Milan's reach.

Having been eliminated from European competition in December and beaten in the Coppa Italia semi-finals by Juventus, the Scudetto remains Inter's only hope for silverware in 2020-21.

Martinez is now determined to end the club's 11-year wait to become champions of Italy again.

"This is what we are: we're united, we work every day to give our best and to reach as high as we can, and today we proved it," Martinez told DAZN.

"We run and fight together; you can see it on the pitch. We have suffered a lot this year: two eliminations from the Coppa Italia and the Champions League. This [Serie A] is the only goal left and we're fighting for it. We're happy to be ahead of everyone else."

Lukaku became the first Inter player since Benito Lorenzi in 1950 to score in four consecutive league derbies against Milan.

Martinez believes the Belgium international can still get better as he aims to win a first club trophy since the Belgian Pro League with Anderlecht in 2010.

"Lukaku can improve a lot," Martinez said. "He's 27 years old, he works and he makes himself available to his team-mates. He's a great person on and off the pitch and we're happy to have him with us."

Inter were mostly in control of the contest but were indebted to goalkeeper Samir Handanovic in the first three minutes of the second half, as he twice denied Zlatan Ibrahimovic in quick succession before tipping a Sandro Tonali shot over the bar.

"Handanovic is always ready. We're happy because, when we need him, he always responds," Martinez said.

"We also should have been more focused [early in the second half], but we're happy to have played a good game and to have got three points."

Gerard Pique accepted it will be "difficult" for Barcelona to rein in Atletico Madrid at LaLiga's summit after Cadiz snatched a late 1-1 draw at Camp Nou on Sunday.

Atleti's surprise home defeat to Levante a day earlier had given Ronald Koeman's side the chance to move six points behind Diego Simeone's league leaders.

They appeared to be on course to do just that after Lionel Messi marked a club-record 506th league appearance with a 32nd-minute penalty.

Alex Fernandez sealed a dramatic point for the visitors in the 89th minute, though, slamming home from the spot after Clement Lenglet was ruled to have clipped Ruben Sobrino.

The result ended Barca's seven-game winning streak in LaLiga and left them with 47 points after 23 games this season – their lowest tally at this stage of the season since the 2006-07 campaign when they amassed 46 points.

While Pique acknowledged it will not be easy to challenge Atleti for the title, he insisted they will not give up.

"It hurts a lot because Atletico's defeat gave us a chance," he told the club's official TV channel.

"Losing two points is difficult to take. Every game that you do not win, your options are reduced a little. There is an important distance [between Barca and Atleti], not unassailable, but it will depend on the next games. If we get good results, we will have options.

"It's difficult, obviously. We have to try. It's a hard blow. On Wednesday, we have another test against Elche.

"We have to recover our game and feelings because, if not, we could lose more games. We need to raise our heads, improve mentally and win against Elche."

Following the visit of Elche, Barca travel to Sevilla on Saturday.

Franck Kessie had touched the ball only five times before Milan fell behind to Inter at San Siro.

The midfielder proclaimed beforehand that the Rossoneri had no reason to be fearful going into the 174th Milan derby in Serie A history. Far from it. "We'll win the derby and return to the top of the table," he told La Gazzetta dello Sport. "We're a group that has grown through difficulty. We believe in the Scudetto."

That pre-match optimism vanished after those first five minutes on Sunday. So, too, did the sense that this Milan really do believe they can end a 10-year wait to win Serie A. With one swing of Romelu Lukaku's left foot – his crossing remains a hugely underappreciated skill – Lautaro Martinez had an easy header and Inter had it all in their hands: the momentum, the match, and the title race.

Inter now lead the standings by four points, with 14 matches to go, after this 3-0 rout. While that hardly seems an unbridgeable gap, the Nerazzurri have for some time looked the strongest contenders: since exiting European competition in December, they have failed to win just five of 17 games in all competitions, while they have only lost once in the league since Milan won the reverse fixture last October.

Sporting director Piero Ausilio has assembled an experienced squad at great expense, with each arrival tailored to Antonio Conte's exacting standards. It took time, and no little public squabbling, but the Inter boss has finally crafted the sort of team that was expected of him: a powerful, purring results machine.

They were in charge from the moment Martinez planted his header past Gianluigi Donnarumma. They tightened up, harried Hakan Calhanoglu, and broke at speed, and it could easily have been 2-0 or 3-0 before half-time. With a little under half an hour left, it was, as Martinez's poacher's finish and Lukaku's awesome run and strike killed the game stone dead.

In many respects, this result should not have come as a shock. Inter are further down the road towards a restoration of past glories, while Milan have been overachieving for the past year. That they came into this contest just a point off the lead was mostly down to a spectacular run that had long surpassed sustainability. They lost twice in Serie A in the whole of 2020, saw a 27-game unbeaten run only ended by champions Juventus last month and reached the halfway stage of the season with 43 points, their best tally in 60 years.

If it's a surprise that Milan have lost four league games already in 2021, it's only because Stefano Pioli has spent much of the past year defying expectations, imbuing players with the sort of confidence that led to Kessie's unfortunate prediction.

Things could have been different here had it not been for a five-minute masterclass from Samir Handanovic, who twice saved implausibly from Zlatan Ibrahimovic and then tipped a Sandro Tonali strike over just after the interval. But for the 36-year-old's heroics, Milan's early second-half pressure may have given Inter a game to chase, instead of giving them the freedom of the final third to pick through on the counter.

So it was that Lukaku's nerve-settling goal was cheered by the Inter bench almost as loudly as a trophy win. The smiles and high-fives followed; Christian Eriksen was positively beaming as he went off after 78 minutes, his transformation from invisible to undroppable now complete. It showed what Inter know to be true: Serie A is their sole remaining commitment this season and it's firmly under their control.

Andrea Pirlo is not overly concerned by Juventus' poor run of form, although he knows his team must return to winning ways when they face Crotone on Monday.

Juve have not won in three matches in all competitions, following up a 0-0 Coppa Italia draw with Inter – which nevertheless secured their place in the final – with defeats to Napoli in Serie A and Porto in the Champions League.

Their performance against Porto was particularly lacklustre, but Pirlo believes the fixture congestion since the turn of the year is a major factor.

The Bianconeri played nine times in January and have been in action on a further five occasions in February, with two games every week in 2021 until now.

"I speak with the president after every game. We spoke after the game at Porto and he didn't intervene this week," Pirlo told a news conference on Sunday.

"We knew we had played a bad game, there was no reason for him to reproach the team. I raised my voice during half-time in Porto, I didn't like how we played and I didn't like the reaction.

"We switched off at the beginning of the second half and we've been analysing the mistakes this week. There's no reason to raise your voice when you know you didn't do well.

"The players must transform their disappointment into energy for tomorrow's game.

"I am not worried, we had won 11 games out of 13. It was normal to have a drop; unfortunately, we had it in a decisive moment after many games.

"It's normal not to be always focused when you play 15 games in 40 days – it's like we played half of a season in one month and a half.

"We knew it would be an intense season, we are here and we must fight for our targets."

Next opponents Crotone sit rock bottom of Serie A, with just three wins from their 22 games so far, although they are unbeaten in their past two league matches against Juve.

While the strugglers have only once avoided defeat in three successive games against a single top-flight opponent, the Bianconeri have failed to win four of their past seven league meetings with promoted sides.

"It's an important game to continue our path in the title race. It's going to be a tough game because Crotone are not going through a good moment, but they play well," Pirlo added.

"They've kept their philosophy and they are trying to impose themselves in every game."

Cristiano Ronaldo has not scored since February 6 but will look to make Crotone the 78th different side he has netted against in Europe's 'top five' league; only Zlatan Ibrahimovic (79) has scored against more such individual opponents since 2000.

Ronaldo has netted against each of the 17 current Serie A teams he has faced in so far, yet Pirlo said the former Real Madrid superstar is still working hard to improve his free-kick taking.

Since his arrival at Juve in 2018, Ronaldo has attempted 44 shots directly from free-kicks in the league but scored only once.

"Free-kick goals are important, they can decide games, especially against teams that sit deep," Pirlo said.

"Ronaldo is training well and is improving. He is calm and he is convinced he is soon going to score from a free-kick."

Inter moved four points clear at the Serie A summit thanks to a resounding 3-0 derby triumph over faltering rivals Milan on Sunday.

Lautaro Martinez scored twice and Romelu Lukaku was also on target, helping Antonio Conte's in-form side make it five wins in their past six league outings to take a firm grip on the title race in Italy.

This was the first time since April 2011 that the city rivals had met when occupying the top two positions in the table, with that season finishing with Milan crowned as champions.

A repeat for the Rossoneri looks increasingly unlikely as their worrying dip in form continued, though they were somewhat unfortunate to come up against a goalkeeper in supreme form.

Samir Handanovic twice repelled Zlatan Ibrahimovic in quick succession early in the second half before Martinez's second goal of the contest, with Lukaku then putting an emphatic seal on the victory in the 66th minute.

However, it was Martinez who had crucially headed Inter in front inside five minutes. Lukaku initially saw his attempted low cross blocked, but a second, floated delivery picked out his team-mate to head past Gianluigi Donnarumma, making his 200th Serie A appearance.

Milan were grateful Lukaku did not take a glorious opportunity before the break, the Belgian striker failing to apply the finishing touch to Ivan Perisic's inviting cross as he missed the ball completely.

Stefano Pioli's team started the second half with a flurry of opportunities; Handanovic spectacularly turned away an Ibrahimovic header at a corner before producing a point-blank block to again deny the Swede when the ball came back into the penalty area.

Inter's captain also pushed a rising drive from Sandro Tonali over the crossbar, maintaining a lead they soon doubled when a clinical counter-attacking move allowed Perisic to pick out Martinez, who fired in with his left foot.

Lukaku put the game well beyond Milan with a fine solo effort, finishing a powerful run from deep in Milan's half with a low shot that flashed beyond Donnarumma. In doing so, he became the first Inter player to score in four successive Serie A derbies since 1950.
