The entire game we took short corners because we didn’t have any confidence in winning any aerial battle. The entire game our crosses were easily dealt with.
He came on and suddenly we have a different avenue to exploit. For 60 minutes we had Diaby and Bailey fail to create anything of real significance. He came on, had a header on target. Had a flick that went just wide, and had another header that went just wide. But most importantly he gave us an aerial threat that Bailey and Diaby just didn’t give us.
We had our tactics negated by their defence. And we needed something different, that he did.
Hence he ‘made an impact’
