“I think they are getting better, they are not for tomorrow,” Guardiola added.

“Hopefully for Nottingham Forest [in the Premier League on Saturday] or coming games because we need it because we have not a big squad at that moment but it is what it is.

“Look how we prove [ourselves] without them in the last games. Hopefully, they’ll be back soon because we need the competition.”

City also won the Premier League and FA Cup to seal a treble last season but despite that success England defender Kyle Walker said there was no shortage of motivation in the squad.

“It’s our job [to be motivated]. We’re at a massive club for a reason,” he told reporters.

“It comes from within that you have to keep going and be motivated. The manager wants to win more, he doesn’t settle for second and we need to follow in his footsteps.

“What we’ve done is in the past now, it’s a new season. The manager drew a diagram and had us at the bottom of the mountain and we have to climb it again. Going again is what separates good teams from great teams.”
