Manchester City boss Pep Guardiola is delighted with the commitment of Jack Grealish.
City face Sheffield United in the FA Cup semifinal today as they chase the Treble.
On Grealish, Guardiola said: I'm impressed with how professional he is.
Yesterday we arrived at six and he was here making treatment to prepare, just in case he's needed.
He wasn't used, at Villa, to playing three games a week for a long time.
He knows his body and regeneration."
The manager added: We can't forget Jack, last season, came from Aston Villa in the previous season with six or seven months injured.
He didn't have the rhythm he has now. These details can influence a lot.
Sometimes you need a little bit more time but if the mind is there always you can adapt quickly.
Always I believe it's the players when they believe.
For example Bernardo, I had the feeling from day one he could adapt.
Players believe I am playing for Manchester City, I am able to play here, they won the Premier League, in their mindset they are ready to play here.
Of course I am good enough to play here, of course I have the ability.
Some players just need a little bit more time than other ones."
