Despite struggling for regular game time so far this season, Anthony Martial has still managed to be involved in the drama at Manchester United.

The Frenchman has five goals and five assists in 13 appearances, with six of those coming from the bench to make an impact on games.

Marcus Rashford's impressive form for club and country, as well as the plethora of options José Mourinho has in attack at Old Trafford, has resulted in Martial's rotation.

However, his in-and-out role at United cost him a spot in France's latest World Cup qualifying squad, which will no doubt have left the 21-year-old sweating over his place in Russia next summer.

With a chance to show the world what he is all about, Martial will be doing all he can to get himself on the plane to Eastern Europe.

One man who isn't worried about the Frenchman's ability, though, is former Monaco team-mate Dimitar Berbatov.

Berbatov played with Martial for two seasons in the principality before his £50m move to United in 2015.

The Bulgarian is obviously no stranger to surroundings in Manchester himself, having won two Premier League titles in four seasons at the club, including the golden boot award in 2011.

In an interview with ESPN, the former Tottenham striker said he was shocked by the ability in that Monaco squad, many of whom have moved onto pastures new, and that he knew Martial was a star straight away.

"I went into the first training session [with Monaco] and saw Anthony Martial, James Rodriguez, Geoffrey Kondogbia, Yannick Carrasco, Bernardo Silva," he started.

"These young players were flying around me and I was thinking: ‘What the f***? I am too old or are these guys too good.

"Martial had something special and he’s developed. He’ll develop even more.

"You could see how fast and strong he was. The only thing lacking was to be more confident."

The Bulgarian also shed some light on the advice he gave Martial when they played together.

Berbatov told the 21-year-old he had to have more belief in his ability, notably because of his frightening pace.

"I liked playing in defence in training; it helped me understand the defenders well," he added.

"Martial would come towards with me the ball. Sometimes he hesitated; he didn’t want to take me on because he thought I was going to take his ball.

"The self-belief was not there.

"I would say: "Anto, you are so quick, you can go past me. Don’t be afraid to do that to every player because you are so quick." He’s a top guy."
