Tottenham Hotspur are currently four points behind top of the table Leicester City.
Spurs have gone unbeaten through their last 12 Premier League matches, and they are looking like one of the most dangerous sides in England.
However, Pochettino is clearly keen to ensure that his players do not get carried away by their early-season success, and he has still not mentioned the possibility that they could be lifting the Premier League title in May.
"We can't get carried away with ourselves,” Mason said. “We've been doing brilliantly recently but football can change quickly.
"We are young, we are eager to learn and we are working hard on the training pitch. The gaffer isn't going to mention winning the Premier League.”
As things stand, Tottenham are sat in fifth place in the table, but their performances have got progressively better this campaign.
Spurs started their season with a loss to Manchester United, but they have not been beaten since and are going from strength to strength.
Tottenham’s young squad is learning by the game, and their recent 4-1 win over West Ham United was highly impressive.
The Lilywhites are only four points behind top of the table Leicester City, meaning talk of their title credentials has picked up.
Tottenham will be able to further underline their ability to compete in the upper echelons of the table when they take on capital rivals, and reigning champions, Chelsea at the weekend.
