The Brazilian defender was mocked when he returned to Stamford Bridge on the final day of the summer transfer window.
Chelsea had sold him to Paris Saint-Germain for £50million in 2014 and re-signed him just two years later for £34m.
But no one expected Luiz to be better than the extravagant defender partial to making mistakes that Jose Mourinho offloaded to Paris.
Antonio Conte has John Terry, Gary Cahill and Kurt Zouma in his defensive ranks, but injuries to Terry and Zouma after Luiz’s arrival afforded him a chance to play.
And he’s not disappointed – leading the team to some big results, topped off with today’s 1-0 win over Middlesbrough at the Riverside Stadium.
Fans are loving the Luiz they’ve got now and took to Twitter to praise him after his latest display:
Chelsea fans – how impressed were you with Luiz?
