Manchester City boss Pep Guardiola says winning the Champions League last season isn't enough.
City open their defence tomorrow against Red Star Belgrade.
Guardiola said at today's presser: "Tomorrow is the first step. We will try and get the first three points. It is important the players don't feel relaxed; for our club to win the Champions League id incredible, but in perspective, how many won one Champions League? A lot.
"We haven't done anything special with just one, but we are incredibly proud.
"We don't have a big squad. [John Stones, Mateo Kovacic ad Jack Grealish] are getting closer, not for tomorrow but maybe Nottingham Forest or the coming games. It is what it is; we proved ourselves without them but hopefully they are back soon because we need the competition."
On the form of goalkeeper Ederson, the manager also said: "He's getting better. We are a team that normally doesn't concede much and when the opponent arrives he is there. He was there again [against West Ham]."
