Former Everton captain Phil Neville feels Chelsea are paying for having sold Nemanja Matic to Manchester United.

Chelsea were thrashed 3-0 by Roma in tonight's Champions League clash.

Neville stated: "What's gone wrong for Chelsea? One word. Matic.

"It's as simple as that. The minute they sold Nemanja Matic was a mistake.

"When you had Matic sat in front of you, alongside Kante, there was protection.

"Whoever made that decision needs sacking. That is one of the poorest decisions I have ever seen in the Premier League. If you ask any of those Chelsea players who they would want back, they would say Matic.

"You replace him with someone who is going to do the same job! Bakayoko is not that player! He is not a holding midfield player. They didn't replace Matic. I wouldn't have let him out of the building, I would have chained him to the training ground walls!"

Meanwhile, on Chelsea's performance, Neville couldn't believe their defending.

"The mistakes Chelsea have made and the performance has been really poor from an Antonio Conte side.

"Roma dominated the game. It is a really disappointing evening for Chelsea. The mistakes they made for the second and third goal aren't characteristic of this Chelsea team.

"They will need to take a long, hard look at themselves before the game this weekend."
