It's the stick or twist question. Perez will need time to find his rhythm in the team but whether Wenger gives it time is another question. He was too eager to get Bif on and that was a worry. You're right, we will be back a square one soon if Bif scores coming off the bench. I don't even think Perez will have long up front and will probably find himself playing on the wing if that happens.
I don't understand the furore over the penalty. In the Stoke v Man City game two penalties were awarded that would have been deemed 'soft' last season yet, crucially, they were correct decisions. Mike Dean gets a blooming medal for it.
When it happens to Arsenal, we're condemned for being lucky
