Former Manchester United striker Dimitar Berbatov believes Ole Gunnar Solskjaer should make signing Ajax defender Matthijs de Ligt a priority this summer.
United have been desperate for an elite central defender for numerous transfer windows and the problematic area will once again be at the top of their issues to solve when the transfer market reopens.
They have been one of several clubs linked with a deal for De Ligt, one of the most sought after and talented young defenders in the world.
The Bulgarian was also keen to offer his opinion on who United should keep, insisting his former employers must do everything to tie down Paul Pogba.
‘Why is Pogba the problem?,’ he added. ‘They criticise some players more than others, which is unfair. You cannot escape criticism in one form or another — we all have phones and are on social media.
‘He’s not a robot, but if you don’t feel appreciated, what do you do? Go somewhere else. But leaving would be a mistake.
‘I really hope Ole will tell Pogba he will build the team around him to give him the confidence to perform at his best.
