Arsenal manager Arsene Wenger has decided to stick with £32m summer signing Alexis Sanchez as his lone central striker for tonight's Champions League play-off decider against Besiktas, with just two changes from the side which drew 2-2 with Everton last Saturday.
Sanchez was hooked off at half-time against the Toffees on Saturday afternoon, but with Olivier Giroud sidelined he continues to lead the line on a night where Arsenal really need him to deliver.
Two changes, one enforced
Elsewhere Arsenal are back to full strength in central defence as Laurent Koscielny returns from an Achilles niggle to partner Per Mertesacker, which means Calum Chambers drops to the bench for the first time this season.
Aaron Ramsey's suspension means there's also a recall for Santi Cazorla in his favoured wide-left role, allowing Mesut Ozil to take up a central spot and attempt to supply the bullets for Sanchez to fire in the final third.
Big night for central duo
Jack Wilshere and Mathieu Flamini have the job of shoring up central midfield with Mikel Arteta still sidelined by an ankle complaint, while Alex Oxlade-Chamberlain keeps his place after proving a rare bright spot from the bench in Istanbul eight days ago.
If Besiktas provide stubborn resistance Wenger has plenty of attacking options to call upon from the bench, with Lukas Podolski back in the squad and Yaya Sanogo considered fit enough to wait in reserve alongside Joel Campbell.
It promises to be nervy night at the Emitates, but Arsenal will still expect to qualify if they play anywhere near their full potential against a side who spurned a host of chances to break them down in last week's first leg.
