Tottenham right-back insists there is a healthy competition.
Kyle Walker is the team's first choice right-back, but since December, summer signing Trippier has become more and more involved, gaining the trust of head coach Mauricio Pochettino.
His early nervous Europa League performances are behind him, and the defender is proving an asset, especially from an attacking perspective, even netting the winner last weekend against Watford - a side who he provided a winning assist against two months back.
He also admits he relishes the way Pochettino gives him license to get forward.
He said: "When Kyle plays I am in the dressing room encouraging him and wishing him well. We have a laugh together in training. There is no animosity or jealousy, we are mates.”
"The manager wants the full-backs to push forward and play like wingers. I love that."
It is this attitude and camaraderie which has been a key part of Tottenham's success this season, losing only three Premier League games.
