The midfielder was named PFA Young Player of the Year for the second consecutive season last month after an excellent sophomore Premier League season.
Alli’s form, with 17 goals and 5 assists in the top flight this season, has led to him being linked with the likes of Real Madrid in recent months.
Asked whether he would consider a move to another league, the 21-year-old responded with an open answer, choosing not to commit his future to either Tottenham or English football.
“It's important you enjoy the journey, whether I end up at Tottenham for the next 15 years and retire here,” Alli told Sky Sports.
“I think it's important for me not to get too carried away by what will happen in the future. The way football is, anything can happen at any time.
“I will enjoy my time here now," he added. "Who knows what will happen in the future?”
Alli has played an integral part in Mauricio Pochettino’s promising Tottenham side this season, yet is likely to find himself finishing the campaign as a Premier League runner-up.
Tottenham will secure second place if they beat Manchester United in the last-ever game at White Hart Lane on Sunday.
