A paperwork error from Chelsea's side has reportedly prevented the loan deal that would have sent Hakim Ziyech to Paris Saint-Germain.

Ziyech, 29, arrived in Paris on Tuesday to complete the move, with both clubs on board after the former £35million signing struggled to force his way into Graham Potter's plans.

The Moroccan international has made only four starts this Premier League season to go with six brief substitute appearances, collecting his first goal involvement with an assist against Crystal Palace on January 15.

According to The Athletic, Chelsea are the side being accused of failing to submit the necessary paperwork in time for the move to be processed, while an anonymous Paris Saint-Germain source is quoted calling the situation a "Class A circus".

ESPN adds that the French giants believe the paperwork was filed in time and will appeal the Ligue 1 decision, but there is no timetable for the appeal process.

Paris Saint-Germain goalkeeper Keylor Navas joined Nottingham Forest on loan as Steve Cooper's side completed a remarkable deadline-beating signing on Tuesday.

Navas, a three-time Champions League winner with Real Madrid, fell out of favour in the French capital with Gianluigi Donnarumma the preferred goalkeeper for Christophe Galtier's side.

The 110-cap Costa Rica international will add a wealth of experience as Cooper's side attempt to stave off Premier League relegation.

Navas, who won two Ligue 1 titles with PSG after leaving Madrid in 2019, could be in line for his Forest debut in a crucial relegation clash at home to Leeds United on Sunday.

The arrival of Navas, whom Forest have the option to sign permanently at the end of the season, was announced shortly after confirmation of Jonjo Shelvey's signing from fellow Premier League side Newcastle United.

Shelvey has penned a two-and-a-half-year contract with Forest, with the fee undisclosed but expected to be insignificant as the midfielder's Newcastle deal was set to expire in June.

Former Liverpool man Shelvey suggested Cooper was a big draw after discussing the move with Newcastle head coach Eddie Howe.

"It's a fantastic football club that has so much history and I'm really looking forward to getting started," he told the club's website.

"My main goal straight away is to fight for my place in the team and stay there.

"It's not going to be easy because there's a lot of competition for places, but it's a challenge I'm really looking forward to and the competitiveness can only help the team going forward.

"I spoke to Eddie Howe and he had such good words to say about Steve Cooper. I previously knew of him from my time at Liverpool, so I knew what a fantastic coach he was, but meeting him for the first time has been a breath of fresh air.

"He's told me what he expects and the high standards he sets, so I can hope I can come and help the team push to stay in the Premier League.

"I've been in this league a long time, I know what it takes to stay up and what it takes to get a good team to gel, so I'm looking forward to getting started and working with the players that are here."

Paris Saint-Germain will have to wait until June to sign Milan Skriniar after Inter chief executive Beppe Marotta ruled out the move happening before the January transfer window shuts.

The centre-back revealed on Sunday he was joining the French champions, though it was unclear whether PSG would pay the reported €20million fee Inter wanted for the defender to move this month.

Skriniar was left out of Inter's squad for Tuesday's Coppa Italia quarter-final against Atalanta but Marotta stated the Slovakia international will stay in Milan for the rest of his contract before joining PSG.

"There are dynamics whereby players frequently change their shirts," Marotta told Mediaset. "We have to get used to this kind of football.

"It's not what we like, it's not what the fans like, but we compare ourselves with professionals.

"Skriniar made a choice that falls within his rights, we have a duty to respect it.

"We're certain that he will continue to demonstrate the same professionalism and seriousness that he always has in all the months to come before the season is over, and that he's up to the task of continuing to represent this shirt."

Paris Saint-Germain forward Neymar has been ruled out of Wednesday's Ligue 1 match against Montpellier.

The 30-year-old has been in fine form for the reigning French champions this season, scoring 17 goals and assisting 14 more in 25 appearances.

Those 31 direct goal involvements put Neymar level with team-mate Kylian Mbappe and behind only Manchester City's Erling Haaland (34) among players across Europe's top five leagues.

However, the Brazil international will not play any part against Montpellier in midweek as he is suffering from muscular fatigue.

PSG announced the news on their official website on Tuesday, with no timeframe given for Neymar's return to action.

Mbappe and Lionel Messi have been included in Christophe Galtier's 21-man squad for the trip to 14th-place Montpellier, as PSG look for their first win in three league games.

After losing to Rennes and drawing with Reims in their past two matches, the Parisians' lead at the top of Ligue 1 has been cut to three points by Lens.

Christophe Galtier rubbished suggestions he must lose Kylian Mbappe, Lionel Messi or Neymar to balance his Paris Saint-Germain side.

The forward trio, arguably the most talented frontline in European football, have been at the forefront of the Ligue 1 giants' latest title charge this term.

But since the World Cup, where Argentina captain Messi defeated France forward Mbappe in the final, the team have won only two of five top-flight games.

Critics claim the team is too top-heavy, but ahead of Wednesday's match with Montpellier, Galtier scoffed at such ideas.

"We have three incredibly strong attacking players," he said. "Are you saying that we have to lose one of these three players to be balanced? That would be a mistake.

"[Our level] is insufficient though, in terms of points per game. We must quickly find a higher level of play, and above all score points.

"It happens in any season, that there is a bad period. We have a busy month ahead of us. January was not good, but now we are all working to remedy it."

Galtier further acknowledged star men Mbappe and Messi underperformed in the 1-1 draw with Reims, but he stressed the blame lies with the collective rather than the duo.

"Kylian and Leo didn't achieve what they usually achieve on an attacking level, but it is not a question of their state of mind," he added.

"With our organisation and our balance, we must find something else. We are working on it. Whatever the system, everyone has to give more on the pitch."

Chelsea have splashed the cash this month and could break the Premier League record by landing Enzo Fernandez before the transfer window closes on Tuesday.

The Blues have already spent big to bring Mykhailo Mudryk to Stamford Bridge, while Noni Madueke, Joao Felix and Benoit Badiashile are among their other recruits.

Fernandez could follow from Benfica on what promises to be a busy deadline day as clubs across Europe scramble to get late deals done.

It remains to be seen if Arsenal can tempt Brighton and Hove Albion to part with Moises Caicedo.

Joao Cancelo looks set to swap Manchester City for Bayern Munich on loan and Paris Saint-Germain could finally seal a deal for long-time target Milan Skriniar along with Hakim Ziyech.

Stats Perform has picked out the standout transfers that could go through before the deadline.

BLUES TO SHOW THE COLOUR OF THEIR MONEY FOR WORLD-CUP WINNER?

Fernandez emerged as a target for Chelsea following his influential displays for Argentina during their World Cup triumph in Qatar.

The London club have wasted no time in building a new-look squad since a Todd Boehly-led consortium completed a takeover and Graham Potter arrived as head coach.

They have already made huge statements this month, none more so than snaring winger Mudryk from under the noses of Premier League leaders Arsenal.

Chelsea are working on trying to secure the services of Fernandez for a reported fee of £105.5million (€120m), which would break the Premier League record of £100m City paid Aston Villa for Jack Grealish.

CAICEDO A NO-GO?

Arsenal have already raided Brighton to bring wantaway winger Leonadro Trossard to the capital.

The Gunners have failed with big-money offers for centre midfielder Caicedo, who last week made it clear he wants to join the Premier League leaders.

Arsenal are said to be ready to test the Seagulls' resolve again on deadline-day with a third bid of £75m, but Brighton want to keep him for the rest of the season.

If they do not get an offer they cannot refuse, Arsenal could turn to Leicester City's Youri Tielemans or Chelsea's Jorginho.

CANCELO BAYERN-BOUND

Eyebrows were raised on Monday when it came to light that Bayern are poised to bring Cancelo to the Bundesliga from City.

The Portugal full-back Cancelo has fallen out of favour at the Etihad Stadium, having reportedly had a bust-up with Pep Guardiola.

A loan deal would be great business for Bayern as they hunt more trophies and this one is expected to go through.

PSG'S SKRINIAR PERSISTENCE COULD PAY OFF, ZIYECH TO FOLLOW?

While Bayern's move for Cancelo has come late in the window, Skriniar has long since been a target for PSG.

The Inter centre-back is only under contract at the end of the season and with the Serie A giants unable to tie him to a deal, it has been seemingly only a matter of time before he moves on.

PSG should finally get their man before the window closes, with the defender having already confirmed he has agreed terms with the Ligue 1 champions. Chelsea winger Ziyech could also be on his way to the French capital.

Arsenal are still desperate to add a new face in central midfield and will reportedly make late runs at Chelsea's Jorginho and Leicester City's Youri Tielemans before the transfer deadline.

Tielemans is one of Leicester's top talents, appearing in all 20 of their Premier League games this season while contributing three goals and an assist from his 18 starts.

Jorginho is in his fifth season at Stamford Bridge and remains an integral part of Chelsea's squad, making 15 league starts this season, including wearing the captain's armband in their two most recent fixtures.

However, both players are in the final six months of their contracts and are set to become available via free transfers at the end of the campaign, and their clubs may be willing to accept a significantly reduced figure for highly valuable assets.

TOP STORY – GUNNERS GUNNING FOR MIDFIELD ACTION AT THE DEADLINE

According to Football London, Arsenal's pursuit of 21-year-old Brighton and Hove Albion standout Moises Caicedo appears to have been unsuccessful, and they now view Jorginho as an acceptable alternative.

The report states Chelsea are willing to let the Italy international leave, indicating he will become expendable if the impending arrival of Benfica's Enzo Fernandez comes to fruition.

Football London also adds Arsenal will make another push at both Caicedo and Real Sociedad's Martin Zubimendi, but they are considered unlikely options.

Meanwhile, 90min claims Leicester would be more open to allowing Tielemans to leave if they were not locked in a relegation battle, but as it stands they would need a "huge" bid to prioritise a transfer fee over their Premier League survival.

ROUND-UP

– Calciomercato is reporting Leeds United will try to secure Roma's Nicolo Zaniolo after he snubbed Bournemouth, but Roma are unlikely to accept unless the full transfer fee is paid up front.

– According to L'Equipe, Paris Saint-Germain are interested in a loan move for Chelsea's Hakim Ziyech, who would prefer a loan to France instead of a fellow Premier League side.

– Manchester United captain Harry Maguire has rejected a loan approach from Inter and will instead opt to fight for his place, although he will re-evaluate his future at the end of the season, per the Daily Star.

– El Nacional is reporting Liverpool will make a run at signing Chelsea's N'Golo Kante when his contract expires after the season.

– According to Football Insider, Southampton have agreed to meet the £26.2million (€30m) release clause for 22-year-old Braga forward Vitinha.

Christophe Galtier insisted he was not worried with Paris Saint-Germain's poor form since the return to action after the World Cup.

Folarin Balogun's last-gasp equaliser for Reims at the Parc des Princes on Sunday left the defending champions with just one win from their past four Ligue 1 matches.

PSG's lead at the summit has been reduced to just three points as a result, a gap that could have been even less had Lens and Marseille not also been held to a draw on Saturday.

Galtier's side have a quick turnaround before Wednesday's trip to Montpellier and he is pushing for a response from his squad.

"Worried no, disappointed yes. We are not going to hide behind the post-World Cup calendar," he said after the match.

"It's been a few weeks since our performances were not at the same level as in the first part of the season. We must work, we must find solutions, and reconnect.

"A crisis of confidence? I don't think so. Maybe a crisis of complacency, all the demands we had.

"It went haywire for different reasons. It's hard to restart. I have high-level players who cannot accept to be at this level since the beginning of 2023."

With just a few days remaining until the mid-season transfer window slams shut, Galtier confirmed the club intend to be active in order to bolster the squad.

"There are 48 hours left. The club is working on the arrival of at least one player. There are significant constraints with financial fair play," he added.

"We want reinforcement. Will it happen? I don't know. We cannot hide behind the absence of a player. We have quality players in the squad. Everyone must find their level very quickly."

Folarin Balogun stunned Paris Saint-Germain at the Parc des Princes with a last-gasp equaliser to earn a 1-1 draw for Reims.

Neymar opened the scoring early in the second half to give Christophe Galtier's home side the lead, but substitute Marco Verratti was sent off soon afterwards.

PSG continued to have the better chances but could not extend their lead, though the 10 men still looked set to grind out a valuable win to return to winning ways on Ligue 1 duty.

Balogun had other ideas though, latching onto Kamory Doumbia's throughball to slot past Gianluigi Donnarumma in the sixth minute of stoppage time and stun the home crowd.

Milan Skriniar confirmed he has signed for Paris Saint-Germain but is waiting for Christophe Galtier's side to agree the transfer details with Inter.

The Slovakia international's agent Roberto Sistici said on Tuesday there was "no possibility" his client would renew his Inter contract, which is due to expire at the end of June.

PSG coach Galtier, speaking after Monday's 7-0 Coupe de France win over Pays de Cassel, suggested a move for the centre-back was imminent, though he did not clarify whether it would be in January or the end of the season.

It is said Inter are demanding €20million from PSG for the defender to leave this transfer window and Skriniar, despite confirming his move, was unable to reveal when he will join PSG.

When asked by Slovakian outlet Futbalsfz about reports he has signed for PSG, the 27-year-old responded: "Yes, it's true. Now, however, I can't add more details. 

"I'm waiting for the two clubs to find an agreement."

Simone Inzaghi's side are reportedly considering Manchester United centre-back Victor Lindelof or Lille's Tiago Djalo should Skriniar's move be completed this month.

Simone Inzaghi will not "waste time imagining what happens in the future" amid speculation over Milan Skriniar's future at Inter.

Defender Skriniar missed Saturday's trip to lowly Cremonese through suspension, though his absence was not felt too keenly as Inter recovered from an early setback to win 2-1 thanks to Lautaro Martinez's double.

The centre-back has been repeatedly linked with a move to Paris Saint-Germain, but with just over three days of the transfer window remaining, Inzaghi is not worrying about losing Skriniar.

"That is not a question for me, it is for directors [Giuseppe] Marotta and [Piero] Ausilio," Inzaghi told DAZN.

"Milan is a great professional, he is here at the moment and trains to his best. I cannot waste time imagining what happens in the future."

Inter were well worth their win at Cremonese, who are yet to secure a victory in Serie A this season.

Inzaghi's side had 30 shots and got 10 of those on target, albeit they relied on the quality of Martinez to get over the line.

Martinez moved onto double figures for the season with his 21st-minute equaliser, when he reacted sharply to turn home a rebound from Edin Dzeko's volley.

The forward has now scored at least 10 Serie A goals in four separate seasons with Inter, becoming only the third foreign player to achieve that feat in the club's history.

Dzeko supplied the pass for Martinez's second-half winner, and Inzaghi hailed the duo's partnership.

"They are fantastic," the coach said. "They are doing very well but [Joaquin] Correa and [Romelu] Lukaku are also returning to get back in good shape.

"They played about 20 minutes and the team will need them because Edin and Lauti can't play all the games."

Inter moved up to second with their victory, but having lost to Empoli on Monday they are a distant 10 points behind runaway leaders Napoli.

"It was tough against a Cremonese side that in the last few days had knocked Napoli out of the Coppa Italia and picked up a point in Bologna," Inzaghi said.

"I am very happy with the character shown by my team, as after a nasty defeat, conceding an early goal against the run of play could have been really damaging."

Despite Napoli's advantage at the summit of Serie A, Martinez is not giving up on the Scudetto.

He told DAZN: "We are racing only against ourselves, as we dropped a lot of points, it's a big gap at the top and Napoli play [on Sunday].

"We must be calm, focus on ourselves and continue to improve."

Chelsea's busy January is showing no signs of slowing down, despite landing five players already.

The Blues, who are 10th in the Premier League, have brought in Mykhaylo Mudryk, Noni Madueke, Andrey Santos, David Datro Fofana and Benoit Badiashile during this window.

Chelsea are 10 points behind fourth-placed Manchester United and desperate for a top-four finish to bring Champions League football back to Stamford Bridge.

And another signing is now imminent.

TOP STORY –  CHELSEA AGREE DEAL FOR LYON'S GUSTO

Fabrizio Romano claims Chelsea have agreed to a deal with Lyon to sign right-back Malo Gusto.

The 19-year-old will fly to London and undergo medical tests on Saturday, with the player to join the Blues in June 2023.

Lyon will receive €30million plus add-ons and retain the player on loan for the remainder of the season.

OL head coach Laurent Blanc had said the club's board guaranteed that he would remain with the club this season, with the loan solving that roadblock. 

ROUND-UP

– Arsenal will make an improved offer for Brighton and Hove Albion midfielder Moises Caicedo , according to The Telegraph. The Seagulls turned down Arsenal's initial £60m bid for the Ecuadorian, who took to social media to plead with the club to let him go.

– Atletico Madrid are back in for PSG defender Presnel Kimpembe , having been interested in him during the off-season, reports Le Parisien. Kimpembe, who is out of contract in mid-2024, may slip out of favour at PSG with the French champions pushing to sign Inter's Milan Skriniar.

– Real Madrid have ruled out an off-season transfer for West Ham United midfielder Declan Rice , according to The Daily Mail. The report claims Rice has "given his word" to Arsenal boss Mikel Arteta that he will join the Gunners next season.

– Roma midfielder Nicolo Zaniolo has rejected a move to Premier League strugglers Bournemouth despite the club's board travelling to Italy, preferring Milan or Tottenham instead, claims Fabrizio Romano.

– FootMercato claims PSG are readying a bid for Lyon's 19-year-old winger Rayan Cherki. PSG have previously tabled two bids for him.

– Lyon are also set to lose 22-year-old Brazilian winger Tete who will join Leicester City until the end of the season, reports The Sun. West Ham, Brentford and Leeds United were also interested in Tete.

Christophe Galtier has held talks with Presnel Kimpembe to clarify that the centre-back remains one of Paris Saint-Germain's vice-captains.

Kylian Mbappe wore the captain's armband in Monday's 7-0 Coupe de France win over sixth-tier Pays de Cassel in the absence of regular skipper Marquinhos.

Speaking to reporters after the cup rout, Galtier said Mbappe – who scored five times – "deserves" to be second captain when Marquinhos is not available.

Kimpembe, who has not played since November due to a heel injury, took to social media on Tuesday to state he had not been previously informed about Galtier's decision.

However, PSG head coach Galtier has since discussed the matter with Kimpembe to dissipate any misunderstanding.

"I expressed myself badly on Monday," Galtier said at a pre-match press conference ahead of Sunday's Ligue 1 match with Reims. 

"The choices are very clear: Kylian is one of the vice-captains. Every time Kimpembe has been on the field and Marquinhos hasn't been, Kimpembe has had the armband.

"When Marquinhos isn't available, there is another captain. In the Lens match there was neither Kimpembe, Marco [Verratti] nor Marquinhos, so Kylian was captain.

"I decided to have Kylian as captain in the last game because he is one of the vice-captains, not 'the' vice-captain. I've had a discussion with Kimpembe to explain all this."

PSG's victory against Pays de Cassel came on the back of a 1-0 loss to Rennes in their most recent Ligue 1 match as their lead on Lens at the summit was cut to three points.

However, not since September 2020 have they lost successive league matches, while their return of 47 points after 19 matches is their fifth-best ever at this stage.

The reigning champions face a tough test this weekend, though, as they host a Reims side unbeaten in 11 Ligue 1 games – the longest run of any side in the division.

"It will be a difficult match for us to begin this run of games," Galtier said. "They have changed system and coach, and we know it will be a challenge for us.

"We now have Kimpembe back in training and Marco Verratti is back with the group. We have to cope with the calendar and focus more on recovery."

PSG are unbeaten in their past 31 Ligue 1 games at the Parc des Princes, winning 27 of those, and have scored in each of the past 20 on home soil.

Chelsea have spent plenty of money on recruitment during the January transfer window, landing Mykhaylo Mudryk, Noni Madueka, Andrey Santos, David Datro Fofana and Benoit Badiashile.

But the Blues may not be done with transfer activity before Tuesday's window closure.

Chelsea are still eager to bolster their midfield options, having missed out on a few key targets.

TOP STORY – CHELSEA TO MOVE FOR EVERTON MIDFIELDER

Chelsea will move to sign unsettled Everton defensive midfielder Amadou Onana, according to The Times.

The Blues will divert their attention to the Senegal-born Belgium international after missing out on Benfica's Enzo Fernandez and Brighton and Hove Albion's Moises Caicedo.

Onana was given a leave of absence from Everton training earlier this week and is unhappy given the club's plight with Frank Lampard sacked as manager this week.

ROUND-UP

– Ferran Torres could be sold by Barcelona in the off-season, despite only joining the Blaugrana in January last year, reports Sport. Barca have ignored offers for the forward in January, despite some clubs wanting him on loan while the report links Atletico Madrid with the 22-year-old.

– Milan are monitoring the status of Manchester City full-back Joao Cancelo, according to The Sun. The Portuguese has struggled for games since the World Cup and could be open to a move.

– Tottenham are getting closer to completing a deal for Sporting full-back Pedro Porro, reports The Guardian. Sporting are determined to recoup his buyout clause of €45 million (£39.7m), with talks, ongoing since the start of the month, getting towards a conclusion.

– Fabrizio Romano claims Weston McKennie has agreed personal terms with Leeds United however the move hinges on negotiations with Juventus about the transfer fee. Leeds' opening bid was €28m, but the Bianconeri want €35m.

– Everton are plotting a shock £25m move to sign Chelsea's Moroccan winger Hakim Ziyech, claims Sky Sports. Roma are also interested in the 29-year-old too, while PSG are keeping tabs on him, according to Media Foot.

– Nottingham Forest are weighing up a bid to sign 28-year-old Italian midfielder Roberto Gagliardini from Inter, claims Calciomercato.

Milan Skriniar's expected departure from Inter is down to "a problem of management" at the club, former midfielder Wesley Sneijder has told Stats Perform.

Slovakia international Skriniar, who is a confirmed target for Paris Saint-Germain, is into the final five months of his contract after rejecting fresh terms in December.

The January transfer window is therefore Inter's final chance to receive a fee for the centre-back, who is into his sixth season as an Inter player.

Inter have seen a number of players depart on free transfers in recent years, and ex-Nerazzurri midfielder Sneijder has questioned why that is still happening.

"This is a problem of management," he said. "When management is not good it's hard to control all the details. On the pitch it is easier, while off it, it is harder but just as important.

"You cannot let the players say they want to leave, let alone at this very moment. You have to take precautions in time to prevent all this."

Inter are reported to have already lined up possible replacements for Skriniar, with Fiorentina's Nikola Milenkovic among those to have been linked with a switch to San Siro.

While Sneijder believes Inter have the resources to cope without Skriniar, the former Netherlands international called on the Italian giants to take more responsibility.

"Inter have a great squad and won't suffer from this problem, but there will be others," he said. 

"They need someone to take responsibility and say 'enough is enough, now we only talk about playing football and that's it'.

"I don't know who is responsible for [the Skriniar situation], but someone has to tell the players they are there to play."

Skriniar has played 242 times for Inter in all competitions since joining from Sampdoria in July 2017, helping the club to Serie A, Coppa Italia and Supercoppa Italiana success.

Providing an update on PSG's interest in the 27-year-old this week, head coach Christophe Galtier said: "I cannot say if he will arrive in [January] or in the summer.

"He is a player we've been tracking for a long time. In fact, we thought that we had already got him last summer."

Skriniar may have already played his final game for Inter after his sending off against Empoli on Monday, with that 1-0 loss leaving Inter 13 points behind runaway leaders Napoli.
