The left-back has played only 20 minutes of Premier League football for Spurs this season after a summer move from Swansea City.
"It would be silly of me to say that it's not sometimes hard and frustrating for me. But you put those feelings aside for the benefit of the club, you can't let them affect your football," he told Sky Sports News.
"As a player you have to be patient if you want to get an opportunity. I could be one of those players who sulks and moans around the place, and takes being left out poorly. My attitude is just to work hard every day and hopefully that will get me in the team.
"Sometimes you do have to keep things inside, and I make sure all those feelings are kept well away from the club and the rest of the squad. If you do have those feelings it is not healthy for the team to bring it out around them."
The Wales international has started all of Tottenham's Capital One Cup and Europa League commitments thus far.
