Juventus coach Antonio Conte is standing by new signing Marco Borriello.

The AS Roma forward's arrival on-loan has upset a section of Juve's support.

"Marco has only been training with us for a week, so his physical fitness is not yet up to the level of his teammates," said Conte. "I haven't decided yet whether to call him for this game.

"I understand the fans are upset, but we have made it very clear Borriello never turned down the Juventus shirt. Therefore I expect everyone to stick together, both inside and outside the squad, because we are still under construction. I'm convinced our fans will embrace us, becoming once again the 12th man."
