Nemanja Matic's future at Manchester United is becoming increasingly clouded.

The Sun says Matic trained for just 24 minutes of Wednesday's session, raising concerns about his long-term future at the club.

It comes just days after the Serbia international snubbed United's black-tie gala dinner, instead choosing to dine out with Wolves striker Patrick Cutrone.

The former Chelsea man also hinted that his time at Old Trafford could be coming to an end by responding to a meme on Instagram linking him with a move to Jose Mourinho's new club Tottenham.

Matic only took part in the start of the session and was seen leaving United's Carrington training ground early in his Mercedes 4x4.

He has already been linked with a January exit and this latest incident is likely to only increase speculation.
