Liverpool's slow start to the second half was a contributing factor to Saturday's 2-1 defeat at the hands of Manchester United, and was the main source of Kenny Dalglish's Old Trafford frustration.
After a goalless first-half, Wayne Rooney netted two quickfire goals within five minutes of the restart. Luis Suarez grabbed a consolation for the visitors but it was not enough to avoid defeat.
"Obviously the two goals coming as quickly as they did made it really difficult for us to try and get anything from the game," Dalglish explained. "But to the boys credit they got back into it and got a goal when Luis got on the end of a free-kick.
"De Gea made a good save right at the end but overall I think you would say they were the better side, but you'd expect them to be at home, and the two goals in five minutes gave us a mountain to climb."
In a bid to get back in the game, Dalglish brought on Craig Bellamy, Andy Carroll and Charlie Adam - attacking substitutions introduced in a bid to inspire a comeback.
"We tried to get ourselves back into the game and sometimes it works and sometimes it doesn't," he continued. "We got ourselves a goal but lost the game.
"Any victory you get is not just with 11 players, it's with 14, so we've got a big squad of players, a great squad and we'll use them as we sit fit, but as I said we left ourselves a mountain to climb with the two goals we lost."
