Former Arsenal star Freddy Ljunberg headed to Seattle?

He is regarded as one of the top fifty players of all time at ARSENAL but looks set to become a DESIGNATED PLAYER for the SEATTLE SOUNDERS. FREDDY LJUNBERG, 31 has already been to SEATTLE and is reportedly heading back this week which makes one assume that the former Swedish international is about set to become a SOUNDER.
Ljunberg last at West Ham has retired from the Swedish national team so this is a DP that will be around.
The only concern is the artificial surface but this will be a marquee signing of a former Calvin Klein model.
Is this a good move from Seattle.
