Suso has committed his future to Liverpool after signing a new long-term contract.
The Spaniard, 18, moved to Anfield in 2010 from hometown club Cadiz and has impressed this season after being promoted to the first-team squad by Brendan Rodgers.
After signing the contract, Suso told the club's official site: "I am really happy. Liverpool are one of the biggest clubs in the world and this is the right place for me.
"I am happy Brendan has shown trust in me. I had no questions about signing a new deal and I am really glad to have done so.
"I am comfortable here. I have played some games for the first team and I hope to continue doing that, but I need to work hard every day for that to happen. This is one of the best days of my life."
Rodgers has singled out Suso's emergence as a symbol of what the club's academy system is trying to achieve. "We are all delighted Suso has committed his long-term future to Liverpool Football Club," he said.
"At 18, he has demonstrated outstanding technical qualities but also shown very good temperament to play for such a prestigious club. His commitment is very good news for all our young Academy players and the excellent work taken place by the Academy coaches and staff."
Suso is one of a number of youthful prospects to break through into Liverpool's first-team squad this season alongside Andre Wisdom, Raheem Sterling and Jack Robinson.
