Lyon went three points clear on top of the UEFA Champions League Group E after destroying Debrecen 4-0 on Tuesday, while Liverpool slumped to a 2-0 defeat at Fiorentina. In Hungary, Lyon's Kim Kallstrom broke the deadlock only after three minutes with a half-volley that bounced off the ground before hitting the net. Ten minutes later, Miralem Pjanic added the second with a curling free-kick. Sidney Govou headed home a corner-kick in the 24th minute. His effort touched a defender elbow and the goalie's palm before settling into the net. Bafetimbi Gomis completed the route 5 minutes after the interval when he latched onto Kallstrom's long pass to elude the advancing goalie, before his delicate chip went over Debrecen defender Marcell Fodor. In the same group, Stevan Jovetic's brace gave Fiorentina a vital home win over an off-form Liverpool side. The Montenegro ace beat the offside trap and went one-on-one with the keeper, thanks to a Cristiano Zanetti through, to slot home with aplomb. Nineteen-year-old Jovetic notched the second after diverting a Juan Manuel low shot into the net. Fiorentina are now second with three points, while Liverpool are languishing in third place on as many points. Lyon are at the top of the group with six points, while minnows Debrecen are bottom with no points.
