Dimitar Berbatov says Bruno Fernandes still needs to work on the defensive side of his game.
The midfielder has been superb since joining Manchester United in January and in midweek scored a brace to help the Reds to a 4-1 win over Istanbul Basaksehir.
On another day, the 26-year-old may have had a hat-trick but he opted to pass up the opportunity to take a penalty, instead letting Marcus Rashford score from the spot.
Yet Berbatov says the Portuguese star can still contribute more defensively despite his attacking talents.
The former United striker argued that Ole Gunnar Solskjaer is having to play a defensive midfielder in order to cover for Fernandes when out of possession.
Despite this, Berbatov still feels Fernandes is doing everything that Solskjaer would have asked of him.
Speaking to Betfair, Berbatov said: “Fernandes has impressed me so much and the only weakness I see in him is his defensive side. He can improve a bit there.
“He’s an attacking midfielder, though, who creates chances, scores goals and up the pitch is where he has his power.
“That’s why I think it’s good to have someone in the team to cover for him.
“Other than his defensive weakness, he is doing everything that the manager wants from him and, with 20 goals since he joined in January, he’s certainly scored more than people expected.
“He is phenomenal in the passing and scoring department and since he joined the club he is doing everything that he needs to do.”
