Whether that means he's got the players already or he's going to have to bring them in throughout three or maybe four transfer windows, I believe he should get that and we should judge him then".
Cech, 36, insisted he is comfortable with a new style of play under Emery which places an emphasis on playing out from the back. His experience here in Arsenal and the Premier League is very important and will give us all the information and performances in his quality.
