Torino coach Giampiero Ventura is unsure of keeping hold of skipper Kamil Glik.

The Poland defender, despite penning a new deal less than a year ago, is being linked with a sale this summer.

Arsenal, Tottenham, Manchester United and Everton have been linked with Glik jut this month.

Ventura said: "He's had continuous and constant growth, it is right that he is a wanted man.

"In the case of him staying, we could aim even higher. But the market can influence certain decisions."
