Jose Mourinho admits Nemanja Matic is not completely fit for Manchester United’s clash with Arsenal but insists the midfielder demanded to play.

The 29-year-old suffered an injury in the 4-2 win over Watford on Tuesday evening and was forced off early in the second half.

Before the match, Mourinho claimed that Matic was a doubt to face Arsenal but the Serb was named in United’s starting XI on Saturday.

‘He wants to play,’ Mourinho told BT Sport.

‘I’m not sure that he’s completely fit to do it but he wants to play and I trust his experience.

‘I trust his feeling and we start with him because he’s an important player for us.’
