Arsenal's Champions League Clash with Bayer Leverkusen: Selection Headaches and Key Updates

Arsenal head to Germany on Wednesday night with the stakes exactly where Mikel Arteta likes them: high, unforgiving and with a few selection headaches thrown in for good measure.

A last‑16 trip to Bayer Leverkusen would be daunting enough without a crowded treatment room, but Arsenal’s manager is at least hopeful that this week will bring more solutions than problems as he looks to take a significant stride towards the Champions League quarter-finals.

Arteta admitted after the FA Cup win at Mansfield that the victory came at a cost. Declan Rice, Gabriel Magalhaes and Martin Zubimendi were all left out of that tie, each managing their own fitness issues rather than simply being given a breather. Then, during the game, Riccardo Calafiori and Leandro Trossard both succumbed to muscular problems, adding a fresh layer of concern ahead of the European clash.

The Spaniard is expected to give a clearer picture in his pre-match press conference on Tuesday, when updates on Calafiori and Trossard will be near the top of the agenda. At this stage, Arsenal are braced for a late call on both.

They are not the only worries. Mikel Merino, Ben White and captain Martin Odegaard remain sidelined, and while there is quiet optimism around some of the absentees, there is still no firm indication that either White or Odegaard will be ready to walk straight back into the starting XI in Germany.

Then there is William Saliba. The Frenchman has missed Arsenal’s last two matches with an ankle problem, and his presence – or absence – could shape the entire feel of the back line. If he comes through training and is passed fit, he will almost certainly resume his partnership with Gabriel at the heart of the defence. If he does not, Arteta will have to get creative.

What is not up for debate is the goalkeeper. David Raya will return between the posts after the heavy rotation at Mansfield, where Arteta shuffled his pack more than at any point this season. That Cup tie was always going to be a staging post rather than a statement; Leverkusen away is the one that truly matters.

Assuming Saliba makes it, the blueprint is relatively clear. Gabriel would line up alongside him, with Jurrien Timber and Piero Hincapie operating as full-backs. Timber’s versatility and Hincapie’s ability to slide inside give Arteta tactical flexibility mid-game, something he has leaned on in the biggest fixtures.

In midfield, Arsenal are planning as if Rice and Zubimendi will both be available to start. If that proves the case, they are automatic picks. Rice’s authority in front of the back four and Zubimendi’s ability to knit play together make them the natural axis for a high-pressure European night.

The third midfield spot is where things become more intriguing. Eberechi Eze has thrust himself into contention after his eye-catching performance and spectacular goal at Mansfield. His flair between the lines offers a different profile, and Arteta has shown before that he is not afraid to reward form. Kai Havertz is the obvious alternative, bringing more physical presence and off-the-ball running, and the final call may come down to how aggressive Arsenal want to be without the ball.

Further forward, much depends on Trossard’s fitness. If the Belgian does not make the trip, the front three almost picks itself. Gabriel Martinelli would be in line for a start on the left, a role he knows well from last season’s Champions League knockout run, when he scored at the Bernabeu against Real Madrid and looked entirely at home on that stage.

On the right, there is no debate at all. Bukayo Saka, fresh from marking his 300th Arsenal appearance with the winning goal at Brighton last Wednesday, remains one of the first names on the teamsheet. These are the nights built for his blend of relentlessness and end product.

Through the middle, Viktor Gyokeres is expected to lead the line. The forward enjoyed a productive group stage, scoring four times in Europe, and arrives in Germany with the confidence of a striker who believes he belongs at this level. His movement in behind and willingness to occupy both centre-backs could be crucial in unsettling Leverkusen’s back line.

Noni Madueke is likely to be kept in reserve as an impact option, the sort of player who can change the tempo of a game from the bench if Arsenal need fresh legs and direct running in the second half.

If Saliba fails to recover in time, the picture at the back shifts. Cristhian Mosquera would be the leading candidate to partner Gabriel in central defence, with Hincapie again offering the possibility of moving inside if Arteta wants to reshape his back four. In that scenario, teenager Myles Lewis-Skelly could be handed a bold start at left-back, just as Hincapie was pushed into the middle alongside Gabriel in the closing stages at Brighton.

Arteta has spent much of his Arsenal reign talking about embracing “big occasions”. This one certainly qualifies. The margin for error in a Champions League knockout tie is thin, the room for excuses even thinner. Injuries, rotations and tactical gambles will all fade into the background once the whistle goes in Leverkusen.

What will matter then is whether the players Arteta has nursed, rested and reshuffled over the past week are ready to deliver when it counts most.
