Alli has been called up for the Three Lions squad for their upcoming Euro 2016 qualifiers against Estonia and Lithuania, despite a relative lack of experience.
Alli has played just seven Premier League matches in his career to date, but Eriksen feels that his 19-year-old teammate is already capable of making the step up to senior international level.
“Definitely," he responded when asked whether Alli was ready to play for his country.
"He has shown what he is capable of in the last few games and he is one of the young lads coming through. We are all really happy for him.”
Alli will have a gentle introduction to international football if he does gain his first cap for England over the international break.
Roy Hodgson's side have already qualified for the main tournament, and Estonia and Lithuania are not considered to be the highest quality of opposition.
For Alli, the call-up still represents a rapid rise to the very top of the game. The midfielder was playing for Milton Keynes Dons in League One just a few months ago, but he has surged to top-flight prominence.
Alli now plays an important role in Tottenham's first-team, and he is rapidly establishing a reputation as one of the finest prospects in the entire country.
