Torres has been criticised for his lacklustre performance against Birmingham City last Sunday.
And one Premier League assistant manager told the Daily Mail this week: "People talk about body language and as a coach it is something you look for.
"I have to say, with Torres it stands out a mile at the moment. It's just not right.
"The question is, is it because he is unfit or because he feels he doesn't want to be there?
"Sometimes, if a player has had an injury it can take ages for him to believe he is fit. Even if the doctors tell him the scans are clear, he can take a while to really feel good.
