Liverpool manager Rafael Benitez was satisfied with his side's performance after they secured their place in the fourth round of the Carling Cup with a 2-1 win over Crewe.
Daniel Agger gave Liverpool a 15th-minute lead from a free-kick before Jermaine Pennant supplied the cross for Liverpool's second goal, headed home by Lucas in the 58th minute, but the margin of the victory over the Coca-Cola League One side should have been greater.
"It was one of those types of games where if you do not score the third goal and finish the game then it can be difficult," he said.
"We were a little bit nervous and we certainly had enough chances to score a third goal.
"We can talk about two good goals - Daniel Agger's free-kick was a fantastic strike and also Lucas is a player that likes to get into the box and I am confident he can score more goals like this.
"It was a very positive result and a positive reaction from the players and perhaps the only thing is that we could not score the third goal."
Benitez explained the decision to introduce Fernando Torres in the second half despite the Merseyside derby at the weekend.
The Spain international had an immediate impact and was twice denied by Crewe goalkeeper Steve Collis.
Benitez added: "We brought Torres on to try and score the third goal - every competition is important so we were trying to create more chances.
"So going forward Torres would give us more space and you could see he had two chances to score which if they would have gone in would have sealed the game."
