I love them. I ensure that every wing player can play multiposition, since I had lot of problems with a single position leftback earlier... But I generally don't have problems with single position midfield players, and they seem to do better that way. All wing players have one thing in common — to cross the ball in, so that's why it seems that multipositional wing players do fairly well. But DC, DMC, MC, AMC/ST — all have different roles.
