to valuable?? 
The guy is past it! People bring up how good his set pieces are but have you ever thought that someone else(Lennon) playing there could have created more chances during open play!? He does nothing during open play and its like playing with 10 men. 
Thank god he's dropped, but i expect McLaren will soon lose his bottle and bring him back in for the next game. This is just a move making him say to the public, "ohh, im not Sven"
