Former Manchester United captain Gary Neville has admitted that he is "really torn" when it comes to Anthony Martial.
Martial, 22, has scored three times in his last two Premier League appearances for United, but has largely struggled for consistency since an excellent debut season at Old Trafford.
The Frenchman is believed to have turned down a new contract at United, although the Red Devils do have the option of a one-year extension this summer.
Neville has said that Martial has "unbelievable talent", and could become "one of the best in the world", but the former right-back is unsure when it comes to the attacker as the full package.
"He's got unbelievable talent, the ability to become one of the best in the world, he just needs confidence, belief and to play in a team that's successful and all of a sudden we'll see the real Martial," Neville told Sky Sports News.
"On the other hand I'd look at it thinking his body language isn't great, his movement off the ball isn't great, he does not make enough moves between the right-back and centre-back. He doesn't drive at people often enough in the final third and commit them, doesn't actually have great quality when the ball is at his feet and he works his way in from the left.
"I am so torn, I think that's where fans are as well, he is a bit of a conundrum in the sense you don't want to lose him and think of what he might become. On the other hand he may need to leave to become what he might become. Diego Forlan had to play in Spain to become one of the best strikers in La Liga, there are players who have to leave sometimes to achieve what they want.
"Then there are sometimes players who achieve what they want, Cristiano Ronaldo it just hit him after three seasons and he became incredible. So I am really torn, it feels like I am sitting on the fence, but it is the reality I am at, I cannot make my mind up on him and I am not sure if that's good or bad three years in."
Martial has scored 40 times and registered 26 assists in 146 appearances for United in all competitions.
