Ex-Chelsea flop is Europe's most important player
Salomon Kalou has the most effective win rate for 2012-13 - see the top 10
Salomon Kalou may have been derided during his spell at Chelsea, but the Ivorian forward has enjoyed some what of a metamorphosis in France after establishing himself as statistically the most important player in Europe.
Kalou left Chelsea in the summer transfer window of 2012 as a free agent after six years at Stamford Bridge, during which period he regularly contracted saddle sores due to the length of time he spent sitting on his backside.
Of the 27-year-old's 251 appearances for Chelsea, Kalou came on as a substitute 107 times, with the Ivory Coast international failing to establish himself under seven different managers during his time with the club.
Hardly an eyelid was batted when Kalou left the club last year with Chelsea fans and staff alike surely relieved to shift the player from their already creaking wage bill, but the player has had the last laugh of sorts during his time with Lille.
Statistics from WhoScored taken from Europe's top five leagues have placed Kalou at the summit of a table detailing the players with the most effective win ratio during the 2012-13 season.
Kalou scored 12 times in 15 starts as a central striker and his goals - particularly from February onwards - contributed significantly to Lille's win ratio in the final months of the campaign.
Lille won 60 percent of the matches Kalou played from the start, compared to a win percentage of 7.7 without him, with the 52.3 percent difference superior to any other player from Europe's most prominent leagues.
