Wumger should try Aneke to play Diaby's position. The same type of player, 6ft4, box to box, technically solid and as strong as ancient european bison.
Well was bringing on the Ox the right choice, did you think he had a good game. Maybe bringing on Theo and putting him up top may have been better.
However had Diaby stayed on i do think we would have benefited from his long legs in the 2nd half.
Pretty much, as soon as Diaby was taken out, we lost a lot of legs in midfield. Arteta and Cazorla are great but they have no legs to compete with more athletic Chelsea's midfield.
