Designated Player Diego Valeri will be a key mover at Portland Timbers according to head coach Caleb Porter.

The Argentine, who has joined on loan from Club Atletico Lanus, will be used as a prime playmaker for the Timbers in 2013 with Porter placing plenty of hope on his ability.

"We're looking for in him something very specific, a guy that can come in and be a playmaking midfielder, a guy that a lot of our attack will go through," Porter told

"And I see him as that guy. He's a very creative player, but also very intelligent, cerebral, smart, understands how to dictate the flow of the game but also a final third player.

"I believe he will produce goals as well. And like a good playmaker does will make players around him better, and we have some very good players in the midfield that will I think complement him."
