The Spain sensation has made incredible progress since making his debut for the club last season, becoming the club's youngest ever goal scorer just a week later and, in the months that followed, the youngest player ever to represent Barca in the Champions League and the European competition's youngest ever goal scorer.

While all eyes were on Lionel Messi following the turmoil that almost saw the striker leave the club last season, his precocious pretender stole the headlines by taking just 15 minutes to open Barcelona's account for the season in spectacular style as they entertained Villarreal.

A perceptive pass by Clement Lenglet began the lightning break from the home side at the Camp Nou, finding wideman Jordi Alba, who charged inside the penalty area on the left and cut a low pass back into Fati's path.

The teenager still had plenty to do from just inside the penalty area, but the calmness with which he dispatched a thunderous effort beyond goalkeeper Sergio Asenjo was worthy of a seasoned superstar and showed why the club were so keen to ward off his suitors with the huge clause in his new contract.

"Such a cool finish," marveled one fan. "Fati may have a big season ahead of him."

Just as the plaudits were raining in for Fati's scintillating strike, he added a second from a similar position following another slick move that began in Barcelona's penalty area and ripped through the middle of the pitch at pace.
