Seattle Sounders coach Sigi Schmid believes Swedish midfielder Freddie Ljungberg may leave the club this summer.

Ljungberg, 33, joined Seattle in October 2008 on a free transfer after leaving West Ham and signed a two-year contract with MLS.

However, the former Arsenal midfielder could now seek a return to Europe after less than two seasons with Sounders, with his contract due to expire in November.

"At this point, he is exploring options," Schmid said. "So we'll see how things proceed in the next three, four, five days.

"Freddie is a great player and he brings energy onto the field. Every time he plays on the field he plays with energy. For us as a team, you have to judge how we play with him or without him.

"I know I have my feelings and my judgements on that thing. But at the end of the day, our backs are against the wall and I think the guys know that."

Ljungberg was named as an MLS all-star after scoring two goals and claiming nine assists in his debut season with Seattle.
