Philadelphia Union head coach John Hackworth insists he will have to wait before expecting anything from new recruit Jose Kleberson.

The former Manchester United midfielder joins the Union from Brazilian club Bahia, in exchange for Freddy Adu, but Hackworth indicated that he was not yet ready to be thrown into the fray for is new club.

"I want to make sure to give him a little bit of time to get integrated," Hackworth told

"Guys have to come in and earn it and one of the last things I want to do is take a guy off a plane and try to insert him in a team that is, at the moment, a solid group."

Hackworth added: "I think as an organization we're going to do something special for him, to have an official announcement when he gets here. But I want to be careful about saying too much, because I don't have exact details of when he'll arrive and when he'll be available for selection."
