Former Tottenham boss Harry Redknapp says David Luiz has it all to prove when Chelsea face Liverpool tonight.
Redknapp wrote for the London Evening Standard: "David Luiz says he is a better defender now than when he left Chelsea but he has to prove that is the case.
"I saw him make some horrendous mistakes during his time at Paris St Germain and he is still prone to a rash tackle, diving in from bad positions and exposing his team-mates.
"There is no doubt he is a good footballer but PSG weren't exactly desperate to keep him, were they? You'd think they would have wanted their money back at least. He isn't a defender in the mould Antonio Conte usually likes and with John Terry injured for Liverpool's visit tomorrow, all eyes will be on him to hit the ground running in his second spell at the club."
