Former Manchester United striker Dimitar Berbatov believes central defence and defensive midfield should be Ole Gunnar Solskjaer's two priorities in the transfer window.

A big summer rebuild at United appears inevitable with the Reds likely to miss out on a top four finish for the fourth time since Sir Alex Ferguson's retirement.

And with 100 days remaining until the transfer window shuts on August 8, former Reds goalscorer Berbatov has identified the two players needed to shore up Solskjaer's side.

“No disrespect to the players, they are good players to play for Manchester United but I think they need players at the back,” Berbatov told the Metro.

“It’s up to Ole to decide how many he needs and what type of defenders he brings in but a centre-back is needed.

“They have issues there. They need someone who can bring the ball out, to give it to Pogba.

“Not someone who just kicks it and makes the forward players fight for the second ball.

“I also think midfield – between the defence and Pogba.”

In regards the attackers, Berbatov believes the current United crop need an injection of confidence if they're to rediscover their form.

Marcus Rashford, Romelu Lukaku, Alexis Sanchez, Anthony Martial and Jesse Lingard have failed to find the net in United's past seven matches.

Berbatov added: “In attack Rashford, Martial, even Lukaku, these guys have the quality.

“The world has changed now, even if you don’t want to see something you’ll see it – on Instagram, social media, somebody swearing at you – you’ll see it.

“You cannot escape it. Even if you’re mentally strong you cannot escape it. You can work with a psychologist or whatever you can do to help but you will still see it.”
