The full-back became Tottenham’s first sale of the summer as Mauricio Pochettino looks to reshape his squad ahead of the 2019/20 campaign.
Trippier, who has penned a three year deal with the LaLiga club to become their first English player in 95 years, made his last appearance for Tottenham in the Champions League final loss to Liverpool – at Atletico’s Wanda Metropolitano home.
And he used his Instagram account on Wednesday evening to express his gratitude to the north London club, where he played more than 100 matches.
However, he initially tagged the NBA basketball team, the San Antonio Spurs (@Spurs), in his post rather than the Tottenham Hotspur Instagram account (@spursofficial) though quickly corrected the error.
“THANK YOU,” he wrote.
“I’ve met some amazing people at [Tottenham] many of whom I now call my friends.
“To the Tottenham fans from around the world – you’ve been amazing. The support you’ve shown me and the team took us to new heights, and with the new stadium I have no doubt that the team and fans have many exciting times ahead!
“Wish everyone at the club nothing but the best.”
A key man in England’s run to the last four of the 2018 World Cup, scoring the opening goal in the semi-final defeat to Croatia, Trippier’s form dipped during the course of the 2018/19 campaign.
But the former Manchester City trainee still made 38 appearances across all competitions last season as Spurs finished fourth in the Premier League, as well as reaching the Champions League final.
