Tottenham attacker Heung-min Son says there's no doubting the desire of the club's fringe players.

Mauricio Pochettino opted to make nine changes to his team for Sunday's FA Cup victory over Aston Villa.

Several players made the most of a rare opportunity to start by producing impressive performances and Son is adamant even those who do not feature regularly are determined to prove their worth to Pochettino.

“We have young and hungry players and in every training session and every week on the bench they learn," he told Tottenham's official website.

"When they play they do really well - the likes of Cameron Carter-Vickers, Harry Winks and Josh Onomah.

"We've got a good squad and everyone is ready to perform. Of course, everyone has to be ready."
