Liverpool goalkeeper Jose Reina is desperate for Barcelona to stop Manchester United from retaining the Champions League crown.
Reina has spent the season trying, unsuccessfully, to stop United securing a third consecutive Barclays Premier League title.
Now the thought of the Old Trafford men winning a fifth trophy this season is too much for the Spaniard.
United have already won the Community Shield, the Carling Cup, the World Club title and the English Premier League.
Reina, a former Barcelona player, believes that is enough.
"I don’t want to see our greatest rivals winning another title," he said.
Reina has been on the winning side against United twice this season, and he added: "The truth is that it is not easy to beat Manchester United twice in a season.
"The key was that we approached both games with nerve and played a passing game from man to man. That is the way to do most damage.
"I believe Barca will play that way and I hope they win because they are a Spanish team and because I do not want our great rivals winning titles."
Meanwhile, Aston Villa manager Martin O'Neill has admitted he would be content for Gareth Barry to see out the final year of his contract, even if it costs the club a sizeable transfer fee.
Villa looked set to lose Barry to Liverpool 12 months ago only for the Reds to pull out of the deal after being unwilling to meet the £18 million valuation of the player.
O'Neill said: "I have had very amicable discussions with Gareth's new agent (Michael Standing). There has been no hidden agenda by any stretch of the imagination.
"Nobody has been rushing around trying to make a quick decision on things. We would love Gareth to stay on, even seeing his final year out if that is the case.
"The chairman's position (Randy Lerner) and mine hasn't really changed. We are not running around worrying about trying to cash in (on Barry)."
Liverpool are expected to again be in the hunt for Barry amid speculation that Xabi Alonso could move to Real Madrid.
