Gary Neville felt Marouane Fellaini was ineffective during the first half of Manchester United's loss to Chelsea on Sunday.

The Belgian was deployed alongside Ander Herrera in front of the back four before he was forced off with an injury sustained in a high challenge from David Luiz.

United went on to lose 4-0 after being two goals down at the break and it was a below par display from Fellaini which contributed to the heavy defeat, according to Sky Sports pundit Neville.

"I think one of the things that was different for United compared to Monday night (against Liverpool) was they had control in the midfield, with Fellaini and Herrera alongside each other," he said on Sky.

"Fellaini played so high in the game today. I am not sure if that was something he was told to do, but it just didn't work. It meant he was detached from Herrera who seemed to be exposed and for United it was not a good 45 minutes.

"I know Fellaini has had a lot of stick over the last couple of seasons with people saying he is not a Manchester United player and it is obvious to see his lack of quality in certain areas, but I thought today he was really poor.

"In the first half he had a really terrible game and it was no surprise he came off and I think Herrera dropped a level after being brilliant at Anfield."
