The Gunners square up to their German opponents tomorrow night at the Emirates.

And, with a big game against Chelsea to play at the weekend, it looks as though the majority of the Arsenal first team will be rested for the match.

Petr Cech, Laurent Koscielny, Alexandre Lacazette, Danny Welbeck, Granit Xhaka, Mesut Ozil and Aaron Ramsey all sat out of the training session at London Colney today and won’t be involved in the game.

Alexis Sanchez, however, looks set to play as he aims to build up his fitness ahead of the match at Stamford Bridge.

Promising academy starlets Reiss Nelson and Joe Willock also trained today and will hope to get some minutes tomorrow.

Arsenal vs Cologne kicks off at 8.05pm.
