Arsenal have been warned that Ben White may be unavailable until at least the middle of January after fresh testing of his injury. BBC Sport reports Arsenal “fear” White’s absence will be for a “minimum of a month” while he recovers from the setback. That best case timeline would see the 28-year-old miss seven or eight matches across three competitions; the absence could stretch longer.

The schedule through mid-January presents a congested spell. Arsenal face Everton in the Premier League on Dec. 20 before a Carabao Cup quarterfinal against Crystal Palace on Dec. 23. League fixtures follow against Brighton on Dec. 27 and Aston Villa on Dec. 30. After the turn of the year Arsenal play Bournemouth (Jan. 3), Liverpool (Jan. 8), then travel to Portsmouth in the FA Cup third round on Jan. 11, and host Nottingham Forest on Jan. 17.

Those fixtures mean a player missing a month could be absent for important matches in the Premier League, the Carabao Cup and the FA Cup. The club had seen improving cover in defence recently. William Saliba returned to the team after injury against Wolves, allowing Piero Hincapié to move to the left as Riccardo Calafiori served a suspension. Jurriën Timber had been required to cover absences in the centre of defence, and White, after being an unused substitute for much of the season, had begun to start games.

When White left the pitch, Myles Lewis-Skelly, the only defender on the bench, was the chosen replacement. That selection underlines the limits of available options on a given matchday and explains why the reported recovery timeline will be followed closely at the club. Arsenal will continue to monitor White’s progress as they plan for the busy fixture list that runs through mid-January.

Ruben Amorim moved to deflect attention from Manchester United’s shape and instead highlighted a mental issue he believes is driving their inconsistent results.

After a chaotic fixture at Old Trafford that prompted widespread discussion about systems, Amorim gave little away. “That is for you to discuss, not me,” he smiled when quizzed by befuddled journalists in his postmatch press conference. He added: “I will say the same thing, you can play with the same players it looks like one thing [and] is another thing,” he cryptically added before addressing the reports which had filtered through the press ahead of Monday’s game. “I know that you guys know that I trained this week the back four—I don’t know how [you know]—but that is a good thing for you guys to discuss.”

Amad Diallo offered a player’s perspective on the club website, stressing adaptability. “I think it depends on the opponent. We work depending on the opponent, when sometimes we play as a 4-4-2, sometimes we play as a 3-4-3, sometimes also we play 4-3-3, maybe people outside don’t see. As a team, we can change. “But the system doesn’t matter for us,” was the key message from Amad. One which Amorim shared.

Amorim underlined the finer points that, in his view, are costing points. “We are not winning games sometimes in the details not because it’s a back four, back three, back five,” Amorim told Sky Sports. “It’s the details that we need to work, understand the momentum of the game. You need to be more clinical, because today against a very good team we create so many chances to win the game.”

A more urgent issue is a pattern of conceding clustered goals. In five matches this season the opposition scored twice within 11 minutes or less: Grimsby (22’, 30’), Burnley (55’, 66’), Nottingham Forest (48’, 50’), Tottenham (84’, 90’+1) and Bournemouth (46’, 52’). After Bournemouth’s quick double Amorim said: “We lost the concentration and they scored two goals”.

Tactical changes against Bournemouth were limited, but the manager acknowledged upcoming selection challenges. Amad and Bryan Mbeumo have played their final matches before heading to the Africa Cup of Nations, and Noussair Mazraoui has already joined up with Morocco. “That is the fun part of being a manager—you will try to find solutions with the players that we have,” he grinned. “After the last season, I think we are ready to cope with whatever they present in front of us. ]

The quarterfinals of the Carabao Cup present a clear pathway to Wembley and a chance for silverware for the leading contenders. Three heavyweights stand out as favourites, while Premier League challengers and a League One side aim to upset the balance.

Cardiff City have a reputation for overperforming in this competition. The Welsh side, who were in the Championship when they reached the 2011–12 final via a favourable run of fixtures, pushed Liverpool to penalties in the showpiece before suffering heartbreak. Now fighting to escape League One, the Carabao Cup has not been a distraction; Swindon Town, Cheltenham, Burnley and Wrexham have all been discarded en route to the last eight. Their reward is a visit from Chelsea.

Chelsea have made life difficult for themselves in cup ties away to Lincoln City and Wolverhampton Wanderers, but Enzo Maresca should name a fairly strong team for the trip to Wales. If the Italian selects even a handful of regular starters, they should conquer Cardiff with little fuss. The Bluebirds will be keen to see a much-changed Chelsea teamsheet on Tuesday, offering hope of a surprise result, but a convincing defeat is the most likely outcome. Prediction: Cardiff 1–3 Chelsea.

Manchester City arrive brimming with confidence and represent a stern test for Brentford. Pep Guardiola’s men have claimed victory in five successive matches and, after their 2–1 win over Real Madrid, they breezed past Crystal Palace on the road last weekend. City have won the trophy four times under Guardiola and dominated the competition between 2018 and 2021, though they have not progressed beyond the last eight since. Brentford possess attacking options in Igor Thiago, Kevin Schade and Dango Ouattara, but an alarming away record in the league — seven defeats from eight — undermines their hopes. Prediction: Man City 3–0 Brentford.

Newcastle, who lifted the trophy last season, face Fulham. Eddie Howe’s side beat Fulham 2–1 at St James’ Park this term with Bruno Guimarães’s last-gasp strike in October. Fulham, inspired by Harry Wilson at times, can threaten, but Newcastle should prevail at home. Prediction: Newcastle 2–1 Fulham.

Arsenal host Crystal Palace a week later because Palace are in the Europa Conference League. Palace have enjoyed two days out at Wembley in the past seven months, conquering Man City in the FA Cup final and beating Liverpool in the Community Shield. Arsenal beat Palace 1–0 on home soil earlier this season and, despite Palace’s capacity to defy the odds, the Gunners should reach the semis. Prediction: Arsenal 2–0 Crystal Palace.
