Speaking to the media at the start of preseason, Howe said: "Sandro Tonali has come back really fit and focused. You can see a change in his demeanour. There is definitely a change in him, in terms of [how he is] feeling as he is closer to playing.
"It is very difficult when you have that stretch ahead of you and you are not going to play competitively for such a length of time. He now looks ready to play, ready to make a difference. He does feel like an absolute new signing and somebody who we desperately missed last year.
"He will feel like he has got points to prove, objectives to hit. He came here with very clear motivations to be successful. He is a deep thinker and someone who wants to do very well. I have no doubt he will."
