Jose Mourinho believes Manchester United should capitalise on Mesut Ozil’s contract situation by making a move for the Arsenal midfielder in the January transfer window.

The Germany international’s current deal expires next summer and he would be available on a free transfer if he fails to agree fresh terms with Arsene Wenger’s side.

United are keen on a deal for the 29-year-old, who has already worked under Mourinho for three years at Real Madrid.

And Mourinho believes his club should seize the opportunity by making an offer for Ozil.

When asked about United’s activity in the January window, Mourinho replied: ‘Nothing to say in relation to that, I’m not a big defender of the January market, but there are players and situations that sometimes you have the chance to do and shouldn’t lose the chance.

‘I don’t like the January market just to buy [for the sake of it], that no.

‘But if you can buy in January a player that you’d buy in June or July, and you have the chance to get him a few months before, then great. But just that.’
