Manchester United boss Jose Mourinho has said that he "cannot guarantee" that Nemanja Matic will feature against Arsenal on Saturday evening.

During the 4-2 win over Watford on Tuesday night, Matic was forced off with a muscle problem and reports have suggested that the Serbian international is unlikely to play in the Premier League clash at the Emirates Stadium.

Mourinho has confirmed that Matic is a doubt for the match, but says that the summer signing will travel down to North London with the squad.

The 54-year-old told reporters: "Matic is a doubt. I hope he can but I cannot guarantee he is selected to go, let's see the feeling before the match, let's see the warm-up.

"I hope he can, I want to, he wants to, but I cannot guarantee."

Matic has started in each of United's 14 league fixtures this season.
