The midfielder was keen to praise the side's defensive displays as their unbeaten run goes on.
Head coach Mauricio Pochettino has a number of options to consider in positions all over the pitch, something which has been demonstrated in his ability to mix the side up for their Europa League games.
Mason has been a part of that squad rotation, with an injury in the draw at Sunderland earlier in the campaign seeing him miss several weeks, although he returned in the recent 5-1 win over Bournemouth.
He had been a starter before then, but knows he faces a fight for his favoured position upon his return.
“I’m happy to be back. We’ve got competition for places all over the pitch and that’s why we’re doing so well,” he told tottenhamhotspur.com.
“Everyone is on their toes, improving each other, the players who aren’t playing are training hard and driving on the players who are playing. The most important thing is that the team has been doing well.”
Mason was also keen to praise the defensive showings from the side this season, as they look to extend their current unbeaten run.
That impressive form has naturally garnered plenty of attention, but the midfielder insists that they are more focused on winning games and progressing than reflecting on what has already been achieved.
“It’s not easy to go nine games unbeaten at any level, let alone in the Premier League – the toughest league in the world,” he added.
“It’s a good achievement for the team but we’re not thinking about that, we’re just concentrating on winning games and progressing.”
