RAFA BENITEZ saw his side torn apart and admitted: We've never played worse. Liverpool fell to two first-half goals from Fiorentina wonderkid Stevan Jovetic, 19 - and were lucky not to lose by a hatful. Manager Benitez said: "Never have I seen us struggle so badly as in the first half - it was a poor performance. "They were on top of us all the time and we didn't do things like we talked about before the start. We were very bad. "Fiorentina did a very good job on us, they pressed us all around the pitch and they pressed us into making mistakes. "If you make mistakes then you pay for them, which is exactly what we did. "We had to change everything and the second half was much better - but it was too late by then." Jovetic made the most of some awful defending to throw Group E wide open. He beat the offside trap to slot past Pepe Reina and then reacted quicker than Martin Skrtel to prod Juan Vargas' cross-shot home. Boss Benitez added: "We knew that Jovetic was a very good player and we expected him to be busy but we gave him too much of an opportunity." Benitez called on his troops to show their true colours in Sunday's trip to Stamford Bridge. He added: "You will see a totally different Liverpool at Chelsea in the league."
