"I think in one week he will be ready to play".
The Italian added: "I think tomorrow will be a very hard game because, mentally, the match after the break is always very hard".
The 37-year-old defender says on Instagram that "after assessing this move with my family, we've decided this is not the right move for ourselves at this time". "I spoke to Eddie Newton (Chelsea's loan player technical coach) about it, but he ended up at Aston Villa", he told the Evening Standard.
"He wants to play with the ball, he wants to play with intensity, to work on the details and to give us all the information he can about the next game and the opponent".
"I think in the coaching staff, I think".
"They are an ambitious club and I have been very impressed with their professionalism".More news: Gas explosions, fires strike Boston suburbs

With Ampadu's stock rising, Sarri said he could feature for the Chelsea first team in the coming future. So he will be very important for everybody here.
And Sarri has confirmed Azpilicueta will lead his side once again when they play host to Neil Warnock's newly-promoted Cardiff on Saturday.
Emerson Palmieri and Davide Zappacosta are major doubts for the game tomorrow after being struck down with a virus while Ruben Loftus-Cheek could also miss out after picking up a knock while away with England this week.
Sarri's smoking ban would be only temporary, "for one, two years, yes".
"Unfortunately at the moment, I am not able to stop. I think it's maybe better to have two days of training [rather than being involved this weekend]".
