Juventus GM Beppe Marotta stands by his summer transfer market decisions.

Marotta insisted that Juve made the right decision in agreeing to sell Ciro Immobile to Genoa in a co-ownership.

"In order to get the best out of youngsters, you have to give other clubs an incentive to do that," he said. "Simple loan moves often don't work in the same way.

"Look at Sebastian Giovinco. We sold a half share in him for €4m to Parma and we signed him back for €11m - now he is a €15m player."
