Pepe Reina has urged the Liverpool board to again splash out this summer in the transfer market.
Reina said: "We are growing up as a team, year in and year out. We need to keep improving all the time because if you do that it gives you an even better chance of winning trophies.
"We will work hard to make this happen, though, and I am sure the manager is already thinking of bringing in some players to help us to do that.
"It is a collective thing. There is no point in three or four players doing well if we do not all do well.
"You win as a team and you lose as a team, so it is all about making progress as a team.
"We are still a young side. We have a couple of centre-backs in their early 20s, Mascherano is 23 and Torres is 24 - we can only get better and better."
