The scathing assessment of Paul Pogba's performance against Barcelona by Gary Neville

Gary Neville criticized Paul Pogba for returning to the form he had shown before Jose Mourinho's dismissal at Manchester United.

The Frenchman was well below Tuesday night as United left the Champions League after a 4-0 defeat to Barcelona.

Pogba was notable during Solskjaer's stay as interim leader, but he has not been at his best since then, despite his two goals against West Ham on Saturday.

Real Madrid continues to be tied to a move for Pogba and Neville has not given way to his badessment of the World Cup winner.

"Pogba now plays as it was before the arrival of Ole," said former United defender BeIN Sports.

"I thought that he was really poor, always rolling on the ball, playing for himself, not lifting him up and not moving, he did not seem interested sometimes.

"But he's a great player, and can be a great player, he just needs to get that concentration back."

United has tilted in front of a good start to the game for Lionel Messi before a shocking mistake by David de Gea offers his Argentine his second and ensures the Barca's progress.

Neville urged the Spaniard to explain and explain his mistake in the midst of criticism.

"I do not know where he comes from. I know people have said De Gea made mistakes in the last 12 months – but not much like that for Manchester United. I do not see the same for Manchester United, "he added.

"I think it's important when you make a mistake like this, in your home country, he's now an experienced player." I hope he's going to come out and explain it, I think it bodes well for him. "
