Juventus midfielder Denis Zakaria can still make a success of his loan move to Chelsea.
The Swiss hasn't played a competitive minute for Chelsea so far this season.
Christian Spycher, who guided Zakaria through the ranks at BSC Young Boys as a sporting director at the time, believes he may yet be given the opportunity to impress.
As quoted by 4-4-2.ch, the 44-year-old said: "Denis is certainly unlucky. He had a fantastic development in Gladbach, was one of the most dominant midfielders until his injury. This came at the worst possible time for him.
"Denis can assert himself, but he needs confidence and top form. He's in a negative circle at the moment because he's not getting any playing time. He needs two or three games in which he can show himself. And then, of course, he has to perform."
