Louis Saha has urged Anthony Martial to rethink any plans of leaving Manchester United.
The attacker is considering his future after a frustrating season which has concluded with omission from the France World Cup squad.
Saha told Omnisport: "Obviously, I would tell him to stay - you do not need to ask this question.
"He's a great player, his pace makes me crazy, he's great, I want him at Manchester United in the best conditions, Jose Mourinho may have to understand how to give him confidence.
"It's a challenge that Anthony Martial has to overcome because I think he can do it."
