Goalkeeper Faryd Mondragón leaves Philadelphia Union

The Union and star goalkeeper Faryd Mondragón agreed to part ways today, upending what had been arguably the team's most secure position on the very first day of preseason training.

There have been multiple reports in recent days out of Colombia that a deal was in place for Mondragón to return to his native country, and wrap up his professional career with his original club, Deportivo Cali.

"It has been an absolute honor and a privilege to be part of the Union family," Mondragón told the team's website. "For family reasons, I have requested the club to allow me the opportunity to finish my career where it started."

Union manager Peter Nowak acknowledged Mondragón's circumstances in that same story.

"We understand that family is important above all else and we decided that it was of the utmost importance to grant him his request of finishing his career with his childhood club," he said. "We wish him the best of luck as he ends his career at Deportivo Cali, the club where he started his career."

So now it's up to Zac MacMath to step up into the starting goalkeeper position. It's also up to the Union front office to find a backup for MacMath, and a good one at that.

The Union will probably lose MacMach during Olympic qualifying matches in March, and again during the summer should the U.S. team make it to London.

What do you think of Mondragón leaving? Who do you think the Union should pursue as a backup to MacMath? Have your say in the comments.
