Tottenham have rewarded Kevin Wimmer with a new five-year contract, just 12 months after he joined the club on a long-term deal from FC Koln.
The Austria international initially penned terms until 2020 when he arrived at White Hart Lane in July last year after spending the previous three seasons in the German Bundesliga.
Wimmer had to wait until January to make his Premier League bow, coming on as a substitute for the injured Jan Vertonghen in a 3-1 win over London rivals Crystal Palace.
The 23-year-old centre-back went on to start nine league games in the absence of Vertonghen, and racked up 21 appearances across all competitions in his debut campaign for Mauricio Pochettino's side.
Wimmer has now signed a one-year extension to tie him to Spurs until 2021.
"I'm very delighted of course to sign the contract and stay with the club for five more years," Wimmer told Spurs TV. "It's a big pleasure for me and I'm very happy to stay with this club."
Pochettino added: "It's important that he's very young and his first season with us was good. All of the squad needs to be ready to take their opportunity and this is what he showed. He competed well and I think it was great for him."
