Holders Arsenal will not be surprised if Middlesbrough beat them in the fifth round of the FA Cup on Sunday after the Championship leaders knocked Manchester City out in the previous round, manager Arsene Wenger said.
Holders Arsenal won through to the FA Cup last 16 with a hard-fought 3-2 victory at Brighton on Sunday as West Ham and Aston Villa also avoided the embarrassment of becoming the latest Premier League clubs to be knocked out by lower league opposition.
