Manchester City boss Pep Guardiola praised the attitude of his players after victory at Crystal Palace.
City went behind early before eventually winning 4-2.
On chasing a second Treble, Guardiola said: “The difference is because we have more injured players than last season.
“We have Kyle [Walker] and Nathan [Ake] today. That means players don't have time to recover.
“We are going to try but it is difficult in all three competitions in my experience.
“To arrive in the final stages you need the whole squad. Almost no chance if you don't have everyone fresh.
“You can do it for short time but for three days, three days – a human being cannot sustain for a long, long time.
“At the same time, they have an incredibly competitive mindset.
“Every week is one week less to the end of season.
“Seven Premier League games left, all the players make an exceptional effort to continue to do it."
