The winger has also admitted that last season was a disappointing one for him but he found positives nonetheless.
The winger has enjoyed an impressive rise in recent years as he has become a regular for both Spurs and England, all after he had spent most of his time at the club out on loan to various sides.
At 24 years old he still has a long career ahead of him, with several areas of his game still to be improved and he says he is specifically focusing on his goal scoring and assist record ahead of next season.
“I’ve got to improve on my goal scoring, my assists,” he told talkSport.
“So that’s what I’m really focusing on this pre-season: working on shooting practice after training and getting my head up a lot more to see teammates in better positions. That’s the next stage to go to so I become more effective in games.”
A disappointing campaign last season
The player also insists he is now in the best shape he’s ever been in after an up and down campaign last season.
He only managed to get 10 Premier League starts to his name under new boss Mauricio Pochettino, with seven appearances from the bench, managing just two goals and two assists in the league as a result.
And he admits that the campaign didn’t go as well as he would have liked, although he is able to take positives from it nonetheless.
“Personally, it was an up-and-down season,” he added.
“I had my times when I was in the team and out the team, but I look at it like: I played in a Capital One Cup final, I scored two goals for England, I scored six goals for Spurs – so you take the positives from it. But obviously it didn’t go as well as I would have liked.”
