The goalkeeper is hoping the Reds can end a four year wait for a trophy by winning the Europa League this season.
"This is the only trophy we can lift this season. It is massively important. All the players here want to lift silverware and this is our last chance to do that," said Reina.
"To win a trophy is always good. We, the players, are the first ones who know that the season hasn't been great. It hasn't been good enough. We should have done better.
"But as long as we have that opportunity to lift a trophy, it is always important for a club and it is for the players. Now it is up to us to lift it up and we have to be persistent.
"No matter what an individual does, it is all about the team. If you play well as an individual, it doesn't make a difference if the team has not performed.
"It was always going to be difficult to repeat the 86 points, as that was a massive achievement and the league was always going to be tougher. But we have had one bad season.
"English football is not easy. We were so close last season, that's why we have been so disappointed with how things have gone this season."
