Torino president Urbano Cairo feels transfer speculation is hurting the form of Joe Hart.
On-loan from Manchester City, the goalkeeper is being linked with Manchester United and Chelsea this week.
Hart hasn't kept a clean sheet since the first week of January and Cairo believes English transfer rumours has affected him.
"There's too much being said about Hart," he told Tuttosport.
"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."
