Seattle Sounders head coach Sigi Schmid believes Argentine midfielder Mauro Rosales will provide plenty for the club this season.

The 30-year old former Ajax Amsterdam and River Plate winger only joined the Sounders just over a week ago and managed to slot in for about 20 minutes in the club's second loss of the season to New York Red Bulls on Saturday.

Schmid said that he expects big things from Rosales who has already made an impact in the dressing room according to the Sounders boss.

"He's an experienced player and obviously technically good. He's played in Europe. He understands training. He speaks great English. I think he's a good person in our locker room," Schmid told the Seattle Times.

"I think people forget that we lost a little bit in our locker room. Sometimes people only look at the playing minutes but when you lose a Tyrone Marshall and a Peter Vagenas those guys are important guys in the locker room in terms of talking to the younger guys, passing on tips and things like that.

"Rosales gives us a little bit of that again because he's got a good personality to him as you guys probably saw in the interview and he can talk to all of the guys on the team and he can share some of his experiences, and he already has. He helps us on the field. He helps us off the field."
