Queens Park Rangers goalkeeper Julio Cesar has risked the wrath of the club's supports after the Brazilian donned the strip of the west London rivals Chelsea during celebrations for the birthday of Blues star David Luiz.
Luiz marked his 26th birthday on Monday with a fancy dress party, and Brazilian compatriot Cesar was one of several star names to attend the bash, held at the flat of the Blues centre-back.
Also in attendance were Chelsea teammates Gary Cahill, Demba Ba, Oscar and Ramires, all of whom got into the spirit in a variety of outfits, including an ill-fitting baby suit and a Zorro themed number.
Cesar attempted to fit in alongside his London adversaries by donning the blue shirt of their employers, complete with matching shorts and socks.
The Brazil international was dressed in a Chelsea kit as a send up of the birthday boy, with Cesar also wearing a curly wig in the style of Luiz's hair, albeit it daubed with the cross of St George.
