"It hurts more and more when we get to November or December every season and have to accept we're out of the title race again," he said.
"Every year seems to be following the same routine. The manager asks for more support in the transfer market in January, while we're all saying to ourselves this should have happened the previous summer.
"The time to act is now, not in January when we're already too far behind. Look at Chelsea - a day after they've lost the league, what do they do? They spend £16 million on a full-back.
"That's the kind of ruthless approach to transfers the Liverpool fans and players want to see, making the signings the manager wants.
"The manager knows where we need to strengthen and the players and fans have faith in Rafa, but he needs the backing to act on his plans.
"There's no point us waiting all summer again and then possibly missing out on the players we need. If we do that we'll just end up going through the same experience as previous years.
"The only way to achieve this is to give the manager the kind of backing which gives us a chance. You only get better when you improve the quality in the squad.
"I'm not just talking or thinking as a player here, but as a fan. This isn't just about what I feel, but about what the fans, the players and everyone who loves the club wants.
"Our supporters deserve more of a challenge than we've put up, but they also need to feel we've a realistic chance of competing.
Like all of us, they'll be watching what's happening at the club over the summer very carefully. They'll be reading the papers every day to find out what's going on, and desperate to feel positive about the future.
"I've always seen summer as a really important period because that's when all the planning gets done.
"League titles aren't just won on the pitch from one week to the next, they're won by managers planning ahead and assembling squads which can cope with the demands of English and European football.
"We have to be doing everything in our power over the next few weeks to prevent another disappointing season."
