Hart was at fault during the 1-1 draw with Crotone as he came off his line to punch a cross but missed the ball which allowed Simeon Nwankwo to net a simple equaliser.
The 29-year-old is currently on a season-long loan from Manchester City and although Torino have made it clear they want to him stay, the Italian club say they cannot afford to meet City’s lofty valuation.
Hart is keen to finalise his future as he wants to ensure he is playing regular first-team football with the World Cup Finals taking place in Russia next summer.
But the Torino chief feels all the speculation surrounding his future is starting to unsettle Hart and says he needs to focus his mind back on football.
Cairo, speaking to Italian newspaper Tuttosport, said:”There’s too much being said about Hart.
“Since this has been happening, his performance levels have dropped. This is already the third time we concede a goal this way and that’s a bit too much.
“It happens and I like him, but come on … He’s a great goalkeeper, though, and let’s see how things evolve.”
Hart’s statistics do not make good reading as he has made the second highest number of errors leading to goals in Serie A and has conceded almost 50 goals in just 30 appearances this season.
