Brighton enjoyed a comprehensive first victory in the Europa League as a goal in either half from Joao Pedro and Ansu Fati eased them to a 2-0 win against Ajax at the Amex Stadium.

It took until the final minutes of a first half that Brighton had dominated for the breakthrough to arrive, Pedro tapping home on the rebound after an opening period in which Ajax – second bottom of the Eredivisie – did little more than look to preserve parity, as Brighton dictated things from the first minute.

The Dutch side have endured their worst-ever start to a league season, and after sacking manager Maurice Steijn on Monday they went down with barely a whimper, Fati’s goal early in the second half laying bare the gulf between Roberto De Zerbi’s team and the four-time European champions.

It was a first half that Brighton controlled but were for the most part frustrated by an organised, obdurate Ajax. Pedro wanted a penalty for a shove in the back inside of three minutes, waved away by the referee with barely a glance, before Brighton’s top scorer on their European campaign tucked the only real chance of the opening exchanges wide of the near post from Karou Mitoma’s cut-back.

Pedro appealed again for a spot-kick, this time with more gusto, when he appeared to be bundled to the ground by Jorrel Hato. The defender was adjudged narrowly to have reached Mitoma’s through-ball ahead of the Brighton striker as the Amex howled for a penalty.

The hosts’ central-defensive pair spent much of the first half 10 yards inside the Ajax half. The plan to lure out the visitors and exploit the resulting space was resisted by caretaker boss Hedwiges Maduro’s team, who seemed content to sacrifice attacking ambition for the sake of clogging the gaps in between their lines.

Simon Adingra had the best chance of the opening half-hour when he lashed a right-footed effort over the bar from Lewis Dunk’s header back across goal, as Brighton’s threat was stymied by Ajax in what was a ponderous first half from De Zerbi’s side.

Mitoma and Pedro’s partnership looked the most likely avenue of success. The pair carved out the clearest opening yet when Pedro dashed into a channel down the right to reach his team-mate’s threaded ball and drove low at goal, only for goalkeeper Diant Ramaj to beat it away with a strong right hand.

The breakthrough came three minutes before the break. Dunk’s pass was weighted into the path of Mitoma who dashed into the box and dragged the ball inside Josip Sutalo to make space to shoot. His effort was pushed out by Ramaj, but only to the feet of the onrushing Pedro who continued his fine European scoring run to end a frustrating half for Brighton on a high.

Fati’s goal, slotted home brilliantly eight minutes after the break, cemented Brighton’s superiority. Adingra began the move from midfield, patiently stewarding the ball until Fati’s run was made, checking inside and feeding the on-loan Barcelona forward who beat his man with a devastating first touch and dispatched deftly beyond Ramaj.

The game had sprung suddenly to life. Fati was inches from making it three and burying Ajax, his driven effort licking inches wide of the post, before Steven Berghuis at the other end struck the upright with Jason Steele beaten, a rare foray forward from the visitors.

It was to be the closest the 2019 Champions League semi-finalists came, as Brighton’s debut European season finally got going in earnest.

Roberto De Zerbi praised an “incredible” reaction from Brighton after they recovered from two goals down at the Stade Velodrome to salvage a point against Marseille and keep alive their hopes of progressing in the Europa League.

Substitute Joao Pedro scored an 88th-minute penalty to earn a 2-2 draw that kept Brighton in contention in Group B following their defeat to AEK Athens two weeks ago, the striker slotting home coolly after Tariq Lamptey had been tripped.

A draw had looked an unlikely outcome when Marseille struck twice in the space two first-half minutes, the first a low finish from former Newcastle defender Chancel Mbemba, then a strike by Jordan Veretout that went through the hands of goalkeeper Jason Steele after Lewis Dunk had given the ball away with a poor miss-kick.

Brighton weathered the Marseille storm, too often giving the ball away cheaply when in possession but surviving to go in only two down at the break, before launching a comeback early in the second period when Pascal Gross slotted home from Kaoru Mitoma’s cutback.

From there on De Zerbi’s team were on top, and it came as just rewards when Pedro was given the chance to level from the spot and salvage their hope of progressing to the knockout rounds.

The manager said he was concerned by the way his injury-hit side have played recently but praised their powers of recovery in the south of France, particularly coming off the back of Saturday’s 6-1 defeat to Aston Villa.

“I want to be honest more than other days, other games,” De Zerbi said. “I think we are not playing well, it’s a very tough period for us in this moment. It’s difficult to show our quality like last season, like a month ago.

“It’s a period where we have to work, but after that in football it’s important the quality of the play and the players, but it’s important playing with heart, passion and the right behaviour.

“I’m really proud of the performance today, of the players. After the defeat 6-1 at Villa Park and the second goal to close the first half at 2-0, this reaction is incredible. For it I am very happy.”

Brighton appeared stagestruck during the first half inside a stadium that rocked with the noise of a vociferous home support.

De Zerbi admitted the atmosphere had been a factor in knocking his players out of their usual rhythm that has seen them win five of their first seven Premier League games this season.

“I know we are not a big team yet,” he said. “We are a small club. We reached the European competition playing very well, showing the incredible qualities of the players, but it’s possible we suffered too much from the atmosphere. (It was) the first game (away) in Europe for Brighton, the players and the fans.

“I’m not a big coach, I’m not used to playing in this competition. We have to adapt, we have to get used to playing in this competition from this moment.

“We can lose the game but we can’t lose our DNA, our spirit, our bravery and passion. This season will be important to progress, to adapt to playing in different competitions, playing three games every week.

“Today we played not more than 30 per cent of our potential.”

Marseille manager Gennaro Gattuso acknowledged his team lost their way after a dominant opening and gave Brighton the encouragement they needed in order to recover.

“The pressure we applied in the first 65 minutes was (good),” he said. “Then we started to press in a different way, not the best way. We should have paid more attention to them.

“With Brighton, if you don’t press well and do the good things, they will punish you. I think the players gave 65 minutes where they were able to press high but it was still not enough.”

Brighton were taught a harsh lesson on their Europa League debut as Greek champions AEK Athens ran out 3-2 winners after a pulsating encounter at the Amex Stadium.

Substitute Ezequiel Ponce struck the winner on the counter-attack six minutes from the end of normal time as Roberto De Zerbi’s side failed to heed the signs after falling behind twice previously in the first half.

Joao Pedro equalised from the penalty spot in the first period then again in the second, both times after VAR had intervened in Brighton’s favour.

The hosts had the better of the play but they lacked the clinical edge of AEK, who scored with two excellent finishes from set-pieces. The first goal was a superb header from Djibril Sidibe, followed by a sliding finish from Mijat Gacinovic as Brighton were undone by nerves and their own naivety.

The opening goal came after 11 minutes and was against the early run of the play.

AEK’s first attack saw them win a corner on the left after a low cross was turned behind. As the ball was whipped in, no one had picked up the lurking Sidibe who with a late dash into the box caught Brighton out with a superb 15-yard diving header that whistled past Jason Steele.

De Zerbi’s side had been badly caught out, and seconds later it could have been two. Levi Garcia, who would torment Brighton in the first period with pace and clever movement, raced beyond the defence and went through on goal, but Garcia’s tame finish was too close to Steele.

Garcia wasted another glorious chance to double the lead from an almost identical position, this time slipping his effort just beyond the far post.

Pedro nodded wide from a free header inside the six-yard box as Brighton finally put together an attack to concern the AEK defence, but within a minute he had made amends for his profligacy.

When defender Ehsan Hajsafi dangled a leg as Pedro looked to cut inside to shoot the referee initially booked the striker for diving. But after a pitchside VAR review the booking was rescinded, Pedro stepped up and coolly rolled his penalty beyond Cican Stankovic to score Brighton’s first European goal.

At that stage it appeared that they had had their reprieve for the way they had left themselves vulnerable to AEK’s threat, but five minutes before the break there was another fine delivery from a set-piece and another critical lapse in concentration.

Brighton held a high line on the edge of their own box as a free-kick was whipped in from 40 yards out, but as blue shirts charged back towards their own goal none could prevent Gacinovic from sliding to get a foot on the ball to turn it beyond Steele.

There was still time for Jan-Paul Van Hecke to deny Orbelin Pineda what would have been a deserved third for AEK on the stroke of half-time.

There was relief then around the Amex when the referee was directed pitch-side for another VAR review after Pedro’s tumble inside the box under Damian Szymanski’s challenge had at first been waved on.

As in the first half, the decision was overturned, and Pedro got to his feet to replicate his earlier composed finish to draw Brighton level again.

De Zerbi was booked for remonstrating too forcefully on the touchline, before Pedro was handed the chance to seal his hat-trick and an opening night win when he spring the offside trap and went one-on-one with Stankovic. This time the goalkeeper got the better of their duel.

Then came AEK’s final sting. A raking ball from the back was nodded out wide by Ponce to Niclas Eliasson, who returned the ball to his fellow substitute. Although Steele blocked Ponce’s shot, the rebound ricocheted off the Argentinian and into the net for the winner.

Joao Pedro and Simon Adingra claimed debut goals as Brighton set aside Moises Caicedo’s ongoing transfer saga to thrash Premier League debutants Luton 4-1.

Club record signing Pedro doubled Albion’s lead following Solly March’s first-half opener by converting a 71st-minute penalty after being brought down by Hatters captain Tom Lockyer.

Carlton Morris slotted home from the spot at the other end following Lewis Dunk’s handball to set up a tense finale but Adingra capitalised on a dreadful error from Pelly Ruddock Mpanzu before fellow substitute Evan Ferguson sealed the Seagulls’ emphatic victory.

Build up to the contest was dominated by news of Albion accepting a British record transfer fee of around £111million from Liverpool for star midfielder Caicedo amid reports he would prefer to join Chelsea.

The 21-year-old Ecuador international was absent from the Amex Stadium as his current club launched their first campaign to feature European football in commanding fashion.

Luton, back in the top flight for the first time since being relegated from the old First Division in 1992, were second best on the south coast and could have lost by more as Danny Welbeck, Pascal Gross and Ferguson each struck the woodwork.

With Caicedo seemingly heading for the exit, Brighton handed debuts to Mahmoud Dahoud, James Milner and Pedro.

Brazilian forward Pedro, whose every touch was booed by the travelling fans following his £30million transfer from Luton’s bitter rivals Watford, should have opened the scoring inside five minutes but he skewed wastefully wide of the gaping goal.

The clubs were facing each other for the first time since the southern final of the Football League Trophy in 2009, with their only previous top-flight meetings coming during the 1982-83 campaign.

Luton did the double over Albion by an aggregate score of 9-2 back then but remained on the back foot, albeit the hosts appeared susceptible to counter attacks.

Albion eventually turned their dominance of the ball into a lead nine minutes before the break.

Kaoru Mitoma was afforded time and space on the left and his inviting, inswinging cross gave the unmarked March a simple headed finish from six yards out.

Albion’s advantage was almost instantly wiped out as Hatters forward Morris thumped a header too close to home goalkeeper Jason Steele from Ryan Giles’ corner before Welbeck hit the base of the right post at the other end.

Despite their limited possession, Luton, who were a non-league club as recently as 2014, were far from overawed in the first half and went into the break with reason for encouragement.

Gross fired against the outside of the left upright from a wide free-kick early in the second period as Roberto De Zerbi’s men attempted to add to their slender lead.

Brighton were in need of a cushion and it arrived 19 minutes from time when Pedro tumbled under Lockyer’s challenge before, as he had done twice in pre-season, firing into the right corner from 12 yards.

Albion looked set to ease to victory on the back of last season’s club-record sixth-placed finish which secured a Europa League place.

Yet Morris’ successful 81st-minute penalty after a cross from substitute Jacob Brown struck the elbow of Dunk briefly brought back the tension.

However, Ivory Coast winger Adingra, who was loaned to Belgian club Union Saint-Gilloise last season, thumped home just four minutes later after Mpanzu inexplicably failed to clear.

Striker Ferguson then rattled the right post with a fine curling effort.

The Republic of Ireland international would not be denied a place on the scoresheet and duly slid home Pervis Estupinan’s low cross deep into added time.
