Juventus captain Alessandro del Piero has sent a 'get well' message to AC Milan striker Antonio Cassano.

Cassano has been undergoing tests in a Milan clinic since Saturday night after feeling unwell on the plane home from his club's 3-2 win at Roma.

"Get well soon Antonio," the Juventus captain said on his Facebook page. "I hope to see you back in action as quickly as possible. Good luck!"
