Torino have enjoyed the England international's experience between sticks since he joined them at the start of the season on loan, after finding no place in Pep Guardiola's side.
However, Hart has been on a downward spiral himself for a number of years now and is nearly a shadow of the shot-stopper that won the Premier League golden glove in 2011, 2012, 2013 and 2015.

However, it has not been all plain-sailing for the former Shrewsbury Town goalkeeper, with only Josip Posavec making more defensive errors (9) than Hart (6) in Serie A this season.
In March, Hart told the BBC's Premier League Show that he does not see himself playing for City again, adding that a return to the Premier League was not top of his wish list.
Hart was at fault for Crotone's equaliser in a 1-1 draw at the weekend and Cairo feels this is partly due to the constant speculation regarding his future.
According to Simon Mullock of the Sunday Mirror, Manchester City turned down the chance to sign Juventus star Paulo Dybala in 2015 during the same transfer window in which they acquired Wilfried Bony.
Now the German gaffer is looking at replacement options, with £20million-rated Hart the most likely. At his best, Hart is one of the best goalkeepers in the Premier League. So although the signing may well be a good one for Liverpool, it might not necessarily be problem completely solved in Liverpool's goalkeeping department.
