yeh great team , i'd say definately buy marco marin , he's a speed machine , german , and he plays in the german ligue (sneijder and robben) , he will connect will with both of them at right mid
Then i would get rid of babel and buy podolski , he fits for left mid and fits with sneijder (bundesliga) then try search for a left wing who plays well along side torres ,
But honestly id change your formation to like 442 or something better , with only like 4 players its hard to say what to do as you can do anything , get a full team and post back , near full team
