The midfielder has enjoyed a successful first season in the Premier League following his debut against Nottingham Forest.
Trailing 1-0 to Nottingham Forest in the Capital One Cup, Mason was brought on for his Tottenham debut by Mauricio Pochettino as he sought to change the game in his side’s favour.
And change it did, as Mason came on to score the equaliser with a 35-yard pile driver, his first for the club. That goal sparked a comeback, with his side going on to win 3-1.
And after spending several seasons away from White Hart Lane on loan, Mason believes that moment was the perfect time for him to make his debut for the club.
"I’m a big believer that everything happens for a reason and the time was right for me," he said.
"I came on against Forest and it was meant to happen. It was a great feeling. It set me up and I kicked on from there.”
Following that performance, it turned out to be a solid season for the midfielder as he established himself in the heart of the Spurs midfield, racking up 37 appearances in all competitions.
Indeed, that moment represented a turning point for Mason, who also made his England debut later on in the campaign, and he believes if he had made his debut earlier, things may have turned out differently for him.
"Perhaps if I’d have played earlier in my career it might not have gone so well,” he added.
