Manchester United have reportedly opened transfer talks Chelsea over a January swoop for David Luiz.
The Brazilian centre-back has fallen out of favour with the Premier League champions following a row with boss Antonio Conte.
He was kept out of the Chelsea side for 12 games before being included against Norwich in the FA Cup draw this weekend.
And now, according to Caught Offside , Mourinho has begun talks with the Stamford Bridge club over a move for the former Paris Saint-Germain man.
No fee has been agreed yet and it is thought that the recent spat between Mourinho and Conte could put the brakes on any transfer between the clubs.
Talking of which...
"Little man!" "Clown!" Everything Mourinho and Conte have ever said about each other
It was a slow burner for a while, but the rivalry between Manchester United boss Jose Mourinho and Chelsea chief Antonio Conte has really ramped up in the last few weeks .
The Portuguese and the Italian have gone head-to-head as they've traded insults on hair transplants, match-fixing and being a "clown" - and the war of words can be traced back to the beginning of last season.
Here's a timeline of just what they've said about each other.
And there's a lot of it.
Mourinho eyes Ozil swoop
Jose Mourinho will make a stunning move to grab Mesut Ozil from Arsenal this month.
The Manchester United manager has been given the go-ahead by the club’s money men to make a bid of up to £35million for the Germany star.
But the Reds face a battle to tempt Gunners boss Arsene Wenger to sell even though Ozil is out of contract in the summer.
Mourinho would prefer a deal then – but fears an auction with Paris Saint-Germain, while Bayern Munich are also keen on the 29-year-old playmaker.
