Gerard Pique claims Fernando Torres will be embarrassed having to play in the Europa League for Liverpool and has urged him to leave the club.
The Barcelona defender, who won the World Cup with the Reds striker, believes he needs to be winning trophies rather than settling for second best.
The former Manchester United player says the 26-year-old will have to leave the Anfield giants and seek success elsewhere.
Pique told the Daily Star Sunday: "There is no way this can go on for Nando. It's just impossible.
"I spoke with him before he committed to Liverpool and he told me he wanted to win things with Liverpool - but if the club didn't invest and show real intent, he would be forced to leave.
"It's really embarrassing for Nando to play in a team of that quality.
"You would not see Messi or Rooney playing in the Europa League - so there is no reason why Nando should be playing there.
"Along with David Villa, he is the best striker in the world.
"He needs to be winning things domestically like he does with Spain."
Pique completed a domestic treble with Barcelona last year and was a World Cup winner with Spain in South Africa this summer.
The defender claims Liverpool are not capable of winning trophies at the current time and has urged the striker to come and join him at Barcelona next season.
"Liverpool have shown already this season they are not capable of winning things - and that's it for him now," said Pique.
"Liverpool are really testing Nando's loyalty.
"For the last two seasons they have promised him they will challenge.
"They haven't delivered on it at all. The ownership of the club looks completely unstable.
"It doesn't look like the manager or the players have any faith in the club.
"There can be no questions when Nando leaves in the summer.
"Players of less quality would have left last summer.
"But he is a decent guy and believed it when they told him they would invest.
"I am not just saying this because I want him to join Barcelona.
"The truth is I don't know if he will.
"It might be Chelsea, it might be Real Madrid, it might be Barcelona.
"But I know he wants to join a club where he can win league titles and European Cups. I would love us to sign Nando in the summer."
