Martial has started a string of games on the left wing to accommodate for Wayne Rooney to play up front, but the England striker has been extremely poor this season.
Rooney has just two goals to his name in the Premier League and his all round performances have been below par, causing Man United fans to call for their captain to be dropped.
It has meant that Martial has been forced out wide, something that is angering supporters. The 19-year-old tends to get outnumbered on the wing and even though he can beat defenders with ease, he is often simply crowded out.
Asked about Martial’s best position, van Gaal said: ”We don’t know yet because he played always in Monaco as the left winger.
“And as a manager I have to see what is the best balance in the team, and that’s not so simple. So I have to decide every week also, dependable of the game plan and the opponent, and so on. We have played with him in the striker’s position, that was not the first time for him, but in Monaco he played always on the left wing.”
When Martial has played up front he has always impressed. His goal against Liverpool and brace away at Southampton both came when he was playing centrally and he has looked most threatening in that capacity. The youngster finds himself helping other people get on the scoresheet rather than looking to find the net himself and with his clinical finishing, it is not the position United will want him to be in.
Van Gaal will hopefully be ready to try Martial through the middle again when CSKA Moscow visit Old Trafford in the Champions League. It is clear that Rooney is struggling and a rest could do him good as he tries to get back to top form and it could be the perfect opportunity for Martial to show what he can do through the middle.
