Dier made 365 appearances for Tottenham in all competitions, tallying 13 goals. Dier played a key role in getting Spurs to the UEFA Champions League final in 2019, when they were defeated by Liverpool, as well as the finals of the EFL Cup in 2015 and 2021. However, he fell down the pecking order under Ange Postecoglou, especially after Spurs completed the signing of Radu Dragusin from Genoa.
