Brendan Rodgers claims Liverpool must sign two marquee players this summer to get the club back to the top and warned his current squad are playing for their future.
Liverpool remain seven points adrift of Manchester United in the race for a Champions League spot having lost 1-0 at Hull on Monday night, which all but killed the club's top four hopes this season.
"For supporters and players it's always great if you can get in those marquee players that can really help you, the one or two that maybe we need," Rodgers said.
"The club are working very hard and the owners will support that. If they're available and affordable, the club will do everything to get them. That's the challenge for me next season: building a team that can get through the rough waters.
"There are a lot of fantastic players but at times in the season when it's tough you have to get through that. If you're going to make a challenge at the top end of the field like we did last year then you're going to need that. We need to refocus and look to improve the squad.
"It's about the quality of players. [Philippe] Coutinho was outstanding tonight but he's having to hold onto the ball for longer periods. He's looking for those runs and type of movement that he's had here for a couple of years and maybe isn't there so much."
Rodgers pinpointed Liverpool's lack of goal threat as once again both Mario Balotelli and Rickie Lambert failed to make an impact.
Italy international Balotelli, who started the match, was jeered by the home supporters throughout another ineffectual performance.
"I think it's clear over the course of the season, not just in this game, that he's struggling," Rodgers said.
However, the Northern Irishman insisted it is not just the strikers who are fighting for their future.
"I spoke to the players at the end and I told them that we have an obligation to fight right to the end of the season," he added.
"It's fair to say every single player here is playing for his future."
