The Argentina international, who has now made two senior appearances for the world champions, enjoyed a marvellous campaign for the Reds, scoring five goals and providing real menace and purpose down the left flank for Erik ten Hag's men.
After returning from injury, he was soon back in top form at the end of the season and was unlucky not to equalise in the Emirates FA Cup final with Manchester City, after coming on as a substitute to pep up the attack.
He was rewarded with a new long-term contract in April and will aim to show he can become a regular starter in 2023/24.
