Liverpool prodigy Suso has threatened to leave the club if his current contract is not improved, IBTimes UK understand.

The Spanish playmaker joined Liverpool from Cadiz's academy in the summer of 2009 during Rafa Benitez's tenure while in the 2012-2013 season he enjoyed his breakthrough campaign on Merseyside, making 20 appearances under Brendan Rodgers.

However, after signing Luis Alberto from Sevilla, Rodgers decided to send him on loan to Almeria last summer to continue his development - where he scored three goals and made nine assists.

Liverpool are now likely to welcome him back into the squad ahead of a busy season which includes a return to the Champions League but with his contract set to expire in 2015 they are trying to secure his long-term future with a new deal.

Sources close to the negotiations have informed IBTimes UK that earlier last month Liverpool handed Suso a five-year deal which was immediately rejected by the Spaniard.

After a productive season in La Liga, Suso is looking forward to return to Liverpool to play Champions League football but is unwilling to do it while still being unvalued by the Premier League club.

Suso is understood to be happy to commit his future to Anfield for the next five seasons but has handed club officials fresh demands including a pay-rise while also requesting assurances over the extent of his involvement during the upcoming campaign.

Suso is awaiting a response from Liverpool but should the demands not be met he has stated he will move away either this summer or once his contract expired in 2015.

Should he decide to move away from Merseyside a number of European clubs will be interesting in securing his services.

Reports in Spain last summer claimed Borussia Dormund approached him while Lille, AC Milan, FC Porto and Sevilla are all believed to be monitoring his situation.

Earlier this season, Rodgers revealed his intention to have Suso back at the squad ahead of the new term.

"The likes of young Suso has had a terrific loan in Spain playing regular first team football. He will come back and come into the squad in the summer and then we will assess where he's at," the Anfield boss said.

"It's good for us to put them into clubs who operate with a similar philosophy. That helps their development and hopefully brings them back ready to play pressurised football at a high level."
