"We've got Thibaut (Courtois) now and, no disrespect to Petr, [there is] a total different kind of age gap there. He's fantastic. He's one of the best 'keepers.
"Last season we had two of the best 'keepers in the world, amongst a few others, so we were really blessed with that.
"Obviously Petr's left now so he's gone to a new chapter and we've got a great 'keeper, and they (Arsenal) have got a great 'keeper."
