The Reds won 1-0 away at Chelsea after a goal by Xabi Alonso on Sunday.
“I think it was really good. We knew it was going to be tough, so thanks to the players, thanks to the fans,” the Spaniard told Sky Sports.
“I think the mentality of the players was good, they were working together and everybody was doing the right things.
“We have shown character to come from behind in some games and now we have shown character against a very good team. We were trying to do everything perfectly.
“But I will keep saying the same thing – one game at a time. We are in a good position and we have to try and keep going and keep calm.”
“The second half they were attacking with more direct players so it was difficult, but were a little bit more comfortable,” he added.
“In the first half they were coming forward and we knew they were a threat, but the players were organised and we played well on the counter-attack.
“I think we now have a better understanding between the players and the belief is good. We have quality, we have a team.”
