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.
A player like Traore who makes the entire crowd furious. When the audience has put such high expectations and it is crushed at the last second. Traore is the one who does that the most, it is only natural that he cannot be transferred to a bigger club because his strength is still not very supportive of the team. He just ran without a perfect execution and this should be his big task to bring out his more potential.
