Per’s knee is not happy. 

    
  
  
    
  

There’s
 a little more room on the Arsenal team plane this morning, as Arsene 
Wenger announced Per Mertesacker, who is suffering from a knee problem, will not be making the trip to the Golden State.

Takuma Asano will also not make
 the trip, presumably because of the myriad of work permit and 
immigration docs it would take for a young Japanese being employed by an
 English club to be able to play in the US. That’s a lot of paperwork in
 a very short time, so Asano will remain behind and work on his game in 
London.
It remains to be seen what 
Arsene’s starting lineup will look like for Thursday’s game, as the 
visiting European team looks to break a two game losing streak against 
the MLS All-Stars. The last visiting team to win was Roma in 2013; MLS 
All-Stars defeated Bayern Munich in 2014 and Tottenham last season.
