NEW YORK (AP) Jason Kreis quit Real Salt Lake to become coach of the expansion New York City FC because he wanted a new challenge.

Kreis, who played for Salt Lake from 2005-07 and coached the team for the past six seasons, left Dec. 10 and was introduced by his new club Friday.

"I believe that in this job as in any other job there comes a time when a new challenge is necessary," Kreis said during a news conference. "I had gotten very comfortable with the surroundings at Real Salt Lake and had, I think, done a lot of things there to build an incredibly successful franchise in an incredible community, and then when an opportunity like this becomes available, I think for me it's just something that you have to take." (MORE)
