Koscielny doubtful

Arsenal's defeat in Munich highlighted the importance of defender Laurent Koscielny, who played in the 2-0 win over the Bundesliga club in October. After being ruled out of the reverse fixture, replacement, Gabriel Paulista struggled alongside Per Mertesacker as Bayern cruised to victory.

Koscielny remains a doubt for tomorrow's game, together with fullback Hector Bellerin. A depleted backline could force Wenger to continue with the back four that started in Munich against resurgent Tottenham striker Harry Kane.

After a stuttering start to the season that saw him net once in 13 appearances, Kane returned to form with a hat-trick against Bournemouth in a 5-1 win before netting the third in a 3-1 victory over Aston Villa.

If Arsenal affords Kane the freedom that Robert Lewandowski and Tomas Mueller enjoyed it could lead to a first away victory in the north London derby for Tottenham since November 2010.
