Sharjah: Star batsman and RCB captain Virat Kohli today termed "unfaired" the criticism directed to his India team-mate Yuvraj Singh for his performance in the recent World Twenty20 loss for India against Sri Lanka in Bangladesh.

"Yuvraj got criticism recently, it's unfaire. He has won us two World Cups (2007 T20 and 2011 50-over), he's a proven match-winner and it's important to back a player like him," Kohli, captain of Royal Challengers Bangalore, said after his side's eight-wicket win over Delhi Daredevils in an IPL match here.
