Mauricio Pochettino praised the performances of the players given their full Chelsea debuts in the narrow Carabao Cup win over AFC Wimbledon, but would not be drawn on reports that the club are on the brink of signing Manchester City’s Cole Palmer.

It took a first Chelsea goal from Enzo Fernandez in the second half to finally see off the challenge of the League Two side and seal a 2-1 victory, after Noni Madueke had equalised from the penalty spot on the stroke of half-time.

Earlier, James Tilley’s penalty had given Johnnie Jackson’s side a shock lead after goalkeeper Robert Sanchez raced from his goal and collided with Harry Pell.

The young trio of Mason Burstow, Ian Maatsen and Diego Moreira all started for the first time in an unfamiliar Chelsea line-up, but it took the introduction of Nicolas Jackson and Fernandez for the hosts to finally settle the tie, with a noticeable difference in the manner of their threat once the pair were brought on in the second half.

Jackson provided the kind of incisive running between the lines that had been missing in the first half, whilst it was a first goal in blue for World Cup-winner Fernandez that finally broke Wimbledon’s resolve 18 minutes from time.

Madueke, Chelsea’s best player in the first period before Pochettino turned to his bench, levelled from 12 yards after he had been tripped in the box by defender Alex Pearce.

Pochettino was asked afterwards about the impending arrival of Palmer, with Chelsea and City reportedly having agreed a £40million fee for the forward, but he refused to comment, preferring instead to praise his team’s progression to the third round.

“I don’t know anything at the moment,” he said. “I cannot talk about players that don’t belong to us. What I can say is nothing at the moment. The club didn’t tell me. I don’t want to talk about a player that has still not signed.

“Maybe yes, maybe no (there will be more transfer business). Maybe you know better than me what is going on.”

Of the performance against the Dons, he added: “It was tough. That’s the beauty of the competition, of the cups. I think for the circumstances we have in the squad at the moment, many players that were involved today, I’m happy with the performance. Many players that made their debut here and it’s tough first time.

“Many positive things. Of course, we have a squad and players that were rested and were on the bench in case we needed. They were fresh to go into the game and of course to help the team achieve what we wanted.

“That’s the beauty of the competition for any club, (when you’re) a Premier League club it’s always difficult to play a team like this, that belongs to this level in League Two. Always the motivation and the desire. It wasn’t a penalty for me, (but) that is the beauty of the competition, these things can happen.”

The manager added that Marc Cucurella, who played 90 minutes at left-back despite reports that the club are in negotiations over a sale to Manchester United, remains a part of his plans until the club informs him otherwise.

“I don’t know anything (about Cucurella). All the players that are involved every day on the training ground with us are in our plans. Then, things happen, it’s the decision of both the club and the player, and if something happens in the next few days, we will communicate to you.”

AFC Wimbledon boss Jackson reflected on a brave performance for his side and took pride in having forced Pochettino to turn to his expensively-assembled bench to seal the win.

“So proud of my players,” said Jackson. “We pushed them all the way, gave them a proper game. We’ve said all week that we weren’t just coming for a day out, we wanted to go toe-to-toe with them. A bit gutted we haven’t pushed them all the way to penalties, but I have to be proud of everyone.

“We knew they were on the bench and to be honest I think their manager was hoping he doesn’t have to use them, so I think it’s testament to my team that we got them to a position in the game where he’s had to make those changes, bringing two hundred million pound players (Fernandez and Moises Caicedo) onto the pitch.”

Chelsea had to rely on reinforcements from the bench to survive a scare as a Mauricio Pochettino’s young selection recovered from a goal down to beat League Two AFC Wimbledon 2-1 in the Carabao Cup second round.

It took a first Chelsea goal from substitute Enzo Fernandez to break the visitors’ stubborn resolve at Stamford Bridge, after they had stunned home fans to take the lead through midfielder James Tilley’s 19th-minute penalty.

Noni Madueke equalised from the spot in first-half added time, as an unfamiliar starting XI made heavy weather of seeing off Johnnie Jackson’s team.

Pochettino brought in three players for their full first-team debuts – Mason Burstow, Ian Maatsen and Diego Moreira – but it took the introduction of a more recognised trio in the second half for them to see off the Dons, who were a stubborn defensive match for their Premier League opponents.

Nicolas Jackson, fresh from his first goal for the club against Luton, was introduced and provided a spark that had been absent, with Malo Gusto and Fernandez helping lend Chelsea the required bite.

The World Cup-winner struck the winner 18 minutes from the end after an unfortunate error from goalkeeper Alex Bass, as Wimbledon went down fighting.

The visitors had been awarded a penalty in the 16th minute when Robert Sanchez flew from his goal in an attempt to deal with Morgan Williams’ deep free-kick, instead crashing his fist into the face of Harry Pell. From the spot, Tilley thumped his kick down the centre as Sanchez dived to his right.

Chelsea almost hit back within minutes when Marc Cucurella, in the side despite reported negotiations over a move to Manchester United, carried the ball to the byline and pulled it back for Maatsen who turned cleverly and struck a low left-footed effort. Bass was relieved to see the ball skid inches past his near post off defender Joe Lewis.

On the half-hour mark, Cucurella again was the provider from the left, this time whipping in a cross which Burstow headed narrowly wide.

Madueke, making his first start under Pochettino, looked Chelsea’s best hope of a first-half response, his penetrating runs and movement off the ball as great a threat to Wimbledon’s lead as the home side could muster. But with the visitors camped largely in their own half, there was little room in which to manoeuvre.

Then on the stroke of half-time came a way back. Madueke, on another darting run, won a penalty as Alex Pearce went to ground with a clumsy challenge. The 21-year-old stepped up and capped a fine individual first period by clipping it coolly past Bass for 1-1.

It was the hosts’ only shot on target of the opening 45 minutes despite enjoying 85% of possession but the arrival at half-time of Jackson ignited something in attack.

His clever footwork and vision found Conor Gallagher and Chelsea’s captain for the night finally warmed the hands of Bass with a right-footed shot that was well saved in the 54th minute.

Fernandez was summoned from the bench and almost made an instant impact, striking at goal from 30 yards and drawing a superb two-handed save from Bass at full stretch. He would not have to wait much longer for his first Chelsea goal.

In the 72nd minute a long ball up from the back was hit by the onrushing goalkeeper straight into Jackson, the ball deflecting into Fernandez’s path to give the Argentinian the simple task of bending it into an empty goal with Bass stranded.

The goalkeeper went a long way towards making amends with a flurry of fine saves to keep the score down.

It was a brave showing from him and his team and might it might have earned them a penalty shoot-out had substitute Ali Al-Hamadi’s last-gasp effort not deflected wide off Axel Disasi.

However, Chelsea’s strength in reserve ultimately eased the Blues into the third round.

Wimbledon boss Johnnie Jackson praised the structure of his side after Ryan McLean’s late strike saw the League Two team down Coventry and reach round two of the EFL Cup.

Championship Coventry were ahead inside 20 minutes, Matty Godden converting from the spot after Joe Lewis chopped down Haji Wright in the box.

And that had looked enough to claim victory, until two late strikes from the Dons turned the contest on its head, Omar Bugiel with the equaliser before McLean’s winner.

“It’s early days, obviously, but any successful team has that base of solidity and defensive structure and I think we looked like that,” said Jackson.

“Coventry had their moments – they’ve got quality players – but if we want to do anything, you got to have that base.

“We’re trying to build a squad where you’ve got competition for places and you’ve got people that are tough to leave out.

“But, when you’re looking behind you to make changes, you know they’re going to come on and have a positive influence on the game.”

Meanwhile, Sky Blues boss Mark Robins rued silly mistakes as his makeshift side snatched defeat from the jaws of victory.

He added: “I don’t think we deserved anything – we could have won if we’d done things right, but we didn’t.

“We didn’t pick the right passes out, we went too long at times and it was just unlike us. Really, they should have been a couple of goals up before the penalty, so we’re a little bit lucky coming in 1-0 up.

“So we speak about that at half time and how we can be better and we end up looking poor in the second half too.

“It’s a new team so I’ve got to be careful what I say; I’m making substitutions for physical reasons rather than tactical reasons at the moment because I’m trying to get everyone fit.”

Ryan McLean’s injury-time strike completed a remarkable turnaround for AFC Wimbledon as they stunned Championship visitors Coventry 2-1.

Mark Robins’ side enjoyed plenty of the ball in south London and deservedly led through a Matty Godden penalty.

Despite creating a number of excellent opportunities, they were dealt two sucker punches right at the death, Omar Bugiel lashing home an equaliser four minutes from time, before McLean’s calm finish sent Plough Lane into raptures.

They should have been ahead within 90 seconds, however, James Tilley inexplicably side-footing wide from eight yards having been found by the weaving Aron Sasu.

Godden and the busy Tatsuhiro Sakamoto were then denied in quick succession by Nik Tzanev in the Dons goal, before Joe Lewis chopped down Haji Wright – Godden making no mistake.

Godden, Gustavo Hamer and Jake Bidwell continued to work the Wimbledon keeper, though the pick was a brilliant reaction save from less than a yard from Ellis Simms.

And just as it seemed Coventry had got away with their profligacy, Johnnie Jackson’s men turned the tie around.

McLean’s cross was met perfectly by Bugiel, striking home having timed his run into the penalty area superbly, with McLean himself showing coolness of mind to turn in a cross deep into added-on time; a remarkable way in which to score his first goal in professional football.

Eddie Nketiah's delightful finish added gloss to a 3-0 win Arsenal were made to work hard for at home to AFC Wimbledon in the third round of the EFL Cup.

Arsenal had won their prior two matches – against Norwich City and Burnley – by just a single goal and looked to be heading for another narrow victory as they struggled to add to Alexandre Lacazette's early penalty.

A late flurry consisted of a vital second from Emile Smith Rowe and Nketiah's gorgeous flick, however, and Mikel Arteta's men have some momentum to carry into Sunday's derby against Tottenham.

Third-tier Wimbledon were far from embarrassed, although they must have feared the worst having conceded inside 11 minutes.

Nesta Guinness-Walker's rash lunge on Gabriel Martinelli on the right side of the penalty area gave Lacazette an opportunity from 12 yards, which he dispatched by sending Nikola Tzanev the wrong way.

But that goal was Arsenal's only shot on target of the first half, even if Tzanev almost gifted them a second when he palmed a looping ball against his own crossbar following Cedric Soares' corner.

A fierce Thomas Partey shot was pushed away after the break, while Nuno Tavares could only direct a far-post header against the upright.

Arteta was forced to bring on Smith Rowe and Bukayo Saka to put the game to bed, however, and the Arsenal number 10 found the breakthrough, prodding in after a scramble with Lacazette claiming the assist.

Nketiah's backheel took the game away from Wimbledon, before Saka twice came close to getting his own name on the scoresheet, whipping a first shot wide and finding Tzanev his match from the second.

Mikel Arteta is backing his kid captains to lead Arsenal out of the gloom as the Gunners launch their quest for EFL Cup silverware.

After a poor Premier League start, Arsenal have strung together 1-0 wins over Norwich City and Burnley, with Arteta pinpointing Martin Odegaard as a key factor behind their improvement.

The Gunners had lost each of their first three top-flight games, but confidence is growing before their first meeting with AFC Wimbledon in the cup on Wednesday.

Arsenal have only failed to go beyond the third round of the competition in one of the last 18 seasons.

Odegaard, who made his move permanent from Real Madrid after a loan spell at Emirates Stadium, scored the winner against Burnley last time out.

Arteta hailed the 22-year-old for the difference he is making, as well as highlighting the importance of fellow young midfielder Albert Sambi Lokonga, who turns 22 in October.

Experienced striker Pierre-Emerick Aubameyang remains Arsenal skipper, but the team now have others with priceless captaincy experience.

"I think we are building some leadership in the group," Arteta said. "It’s a really young group, with a lot of players under 23.

"Martin is the captain of the [Norway] national team and Sambi was the captain at Anderlecht.

"Martin has this capacity to do that with his talent, taking the ball in moments where others probably refuse to, but as well with his attitude, his rhythm and the way he presses and puts people under pressure. He's probably the first to do it.

"I was really impressed with Auba [Aubameyang] as well – I think his rhythm and high pressing was fantastic."

The last lower-league team to beat Arsenal in the EFL Cup were Walsall in 1983, and this is the first time AFC Wimbledon have reached the third round.

But Arteta insisted his focus remains on one game at a time, despite an expected one-sided affair on Wednesday when fringe first-team players are likely to be involved.

"These games are like any other game, an opportunity for anybody to show that he deserves to be in the team and we are wrong," Arteta said, quoted on the Arsenal website.

"Focus, demand the highest standards, prepare the same way or even better.

"There is a lot of coaching now going on around the team. Young players are starting to talk and communicate, and that facilitates a lot of things in the defensive phase.

"After the difficult start that we had in many different aspects, when you start to win two games, you can win the third one. You get more momentum, more confidence, everybody's back, and then you start to create a different feeling."
