Manchester United manager Louis van Gaal has praised Anthony Martial's versatility, saying he believes the forward can play in four different positions.
Martial, 19, has mainly been deployed as a striker for United since arriving at Old Trafford from Monaco in the summer.
However, Van Gaal used the France international on the left wing for the 3-0 win at Everton on Saturday, and the Dutchman says he could also feature in other areas in future.
"He [Martial] can play, in my opinion, four positions," Van Gaal told MUTV.
"He can play at No. 7, as a right winger, No. 11, the left winger, the striker's position and also at No. 10, I believe. But he has played in Monaco always in the left-winger position.
"That is why I put him there against Everton and also because of [Seamus] Coleman. I think he's a very good right full-back, so we could take benefit of the qualities of Martial also."
Van Gaal believes Jesse Lingard -- who came off the bench against Everton -- is also an option on the left, although he accepts the 22-year-old has plenty of competition for a starting spot.
"Lingard's competitor is Juan Mata and his competitor is also, for example, Ander Herrera or Wayne Rooney or, when he is played on the left, because he can also play on the left, his competitor was Memphis [Depay]," he said. "So it's not easy to come in."
