The Reds lost 2-0 to Fiorentina in the Champions League on Tuesday.
“It was a really disappointing night,” Gerrard told The Liverpool Echo.
“We are disappointed with our first half performance. We just didn’t turn up and were second best all over the pitch. We deserved to go in behind.
“There was a reaction in the second half – without creating many clear-cut chances – but we lost the game in the first half tonight.
“We didn’t do what we usually do in Europe. We usually play with a high tempo, pass the ball well and play really well on the counterattack. Those things weren’t there tonight and it was all over the pitch – from front to back.
“Now we’ve got a massive game at Chelsea on Sunday. We have to get this result out of our system quickly and show a reaction at Stamford Bridge.”
“It’s wide open in this group and there is a lot of football still to be played,” the midfielder added.
“It’s important now that we win our next home game against Lyon. If we win all our home games and try to pick up a couple of points in the last two away games then we will be fine.”
