Tottenham Hotspur midfielder Mousa Dembele is looking to put the disappointment of last season behind him and prove his worth to the White Hart Lane faithful over the coming months.

The 28-year-old Belgium international moved to Spurs for around £15m ($23.5m) in the summer of 2012 to fill the gap left by the departure of Luka Modric to Real Madrid – having previously impressed in two campaigns with Fulham.

But Dembele has failed to make the killer impact expected since his arrival in North London. His future at the club has even been questioned after making only 120 Premier League starts during Mauricio Pochettino's debut campaign.

The Argentinian manager, however, claimed last week that Dembele remains in his plans ahead of the new campaign and eventually handed him a starting role in the right flank during the 1-0 defeat against Manchester United on 8 August.

"I think we need to try to provide him [with the help] to show his real quality here. It's true last season was difficult for him, but not only was it difficult for him at Tottenham – with his national team too. It's for that reason we need to try to find the best position for him, to show the quality that he has," Pochettino said last week.

And now Dembele has said he hopes to pay back his boss's faith with an improved performance this campaign.

"I'm happy I started and I just try to develop every time I play. I want to show everyone what I can do. I hope to fight for the team and that's the first thing I'll do, fight for the team and try to do what the manager asks of me," Dembele said to the club's official website.

"There is a good atmosphere in the team and I want to be part of that and prove that I can be important for this club. This season I want to be successful personally and with the team, which is important."

Mousa certainly wants to have more influence in forward areas: "I want to score goals and make goals."

The versatile midfielder scored just one goal last year but believes he can improve those stats in his new role on the right-flank.

"I've played a few games on the right now and I've been able to focus on being dangerous in front of goal and trying to do that more and more. The statistics will show that I need to score more goals so this is something I want to improve this season and show I can be more potent in front of goal."

Despite the defeat at Old Trafford, the Belgium international believes Tottenham took plenty of positives from the game.

"It was the first game of the season, it was a good performance and if we play like that against a lot of teams we'll win the games. [Sergio] Romero made some good saves and I'm sure United had respect for us after that."
