In football there are always some players that they didnt do many things in the pitch but they still playing and this is what we cant understand as football fans...maybe there is somthing inside those players that only managers can see because there is some dettails in football that only managers can take it in consideration
Tactically it forces the other team to have its fullback play more defensively to block that space Traore can use with his pace and strength.
It's not an uncommon tactic, the thing is that usually these kind of players end up scoring a lot of goals and creating a lot of chances. Traore gets into these positions a lot as well, but his decision making is so poor in these situations so he ruins them all.
A really frustrating player to watch if you are his manager. He has the potential to give you something extra, you are relying on it game after game, yet it never happens.
