Suso's agent Jaume Serra has confirmed to IBTimes UK the Liverpool midfielder has agreed personal terms to join AC Milan at the end of the season and has revealed talks to make the deal happen during the January transfer window.
The 21-year-old playmaker moved to Merseyside from Cadiz's academy in the summer of 2009 during Rafa Benitez's tenure.
The Spaniard has since been considered one of the biggest jewels to emerge from Liverpool's youth system and in the 2012-13 season, manager Brendan Rodgers handed him 20 first-team appearances.
After a successful last season on loan at Almeria - scoring three goals and grabbing nine assists - Suso earned a return to Merseyside in the summer.
However, the Spaniard has only made one Capital Cup appearance this term as Rodgers overlooked him during the first part of the season before he sustained a groin injury.
With his contract at Anfield set to expire at the end of the current campaign, his future at the club has been under scrutiny.
IBTimes UK revealed earlier in the season Suso had rejected a renewal offer to commit his future to Merseyside both because of the reduced fee and the lack of playing time in the first team.
Porto have been linked with his services in recent months while reports on Monday 5 January claimed the Spaniard had reached a pre-contract agreement with Milan to move to the Serie A once his contract expires.
Now his agent has confirmed the news to IBTimes UK while claiming Suso and the Italian side want to make the deal happen in the January transfer window as his options to play at Liverpool during the second part of the season look uncertain.
"We have already reached an agreement with Milan to move to Italy at the end of the season," Serra said to IBTimes UK.
"Liverpool already know that Suso will not play at Anfield next season but we are considering him to leave him now. It is not easy though. We will see if Liverpool accept."
IBTimes UK understand the Merseyside club would accept to part ways with the Spaniard imminently should Milan pay cut-price compensation for his services.
Nevertheless, if they do not reach an agreement with the Serie A giants, the starlet will go for free in the summer.
