Kane and Alli have been two of Tottenham’s key players, as they have mounted an unexpected push for the Premier League title.
And Capello believes that the duo can play an important role for England in the future, although he does argue the Three Lions will not be any more successful until the domestic schedule changes.
“There is a new generation and I have been impressed with Jamie Vardy, Harry Kane and Dele Alli, but they need rest at the right time,” he said. “Unless they make changes it will always be difficult to compete in tournament conditions.”
Kane has netted 20 goals in 40 appearances so far this season, and he has been handed a great deal of responsibility by Spurs.
The 22-year-old is the only recognised out-and-out striker at White Hart Lane, but he has managed to avoid injury throughout the campaign so far and he has shown a good level of consistency.
Alli, meanwhile, has been one of the surprise packages of the campaign after having a great impact since signing from Milton Keynes Dons.
The attacking midfielder was brought to the club as a player for the future, but his quality has forced him into the first-team and he has not looked back.
Alli has now made his senior England debut, and he seems set to be part of the Three Lions’ squad at Euro 2016.
