Gareth Southgate named a 27-man squad on Thursday afternoon, which will be trimmed to 23 players for the beginning of the tournament in Portugal. "I think he had a hard season previous year but this has been a lot better".
"Those Champions League nights that we've just had might have had five-fold the numbers so that's always a constant battle".
Yet asked at Wembley on Thursday if he thought it necessary for Kane to feature at the Wanda Metropolitano Stadium on June 1, Southgate replied: 'I don't think it is an absolute he has to play there or he is not ready four days later. It's the biggest challenge of all to compete against each other, then leave that at the door and remember with England we are a team, we support each other.
Southgate led England to the World Cup semi-finals a year ago - the first time they had reached that stage since 1990 - and their success in Russian Federation prompted fervent celebrations from fans back home. The midfielder has also not played since the Champions League quarter-final against Manchester City on 9 April and has since undergone surgery on a groin problem but he, too, has been included in the initial squad. We have got to adapt.
However this is Southgate's captain as well as his most predatory forward, and he clearly wants him as an option for that semi-final encounter with Holland on June 6.
Southgate admitted he was unsure over Kane's fitness, not just for the Nations League but the Champions League final, saying: "That's one of the unknowns".
Southampton winger Nathan Redmond has also been rewarded with a call-up after strong domestic form, while Fabian Delph, Joe Gomez, Jesse Lingard and Harry Winks are all involved after missing the March internationals through injury.
Ruben Loftus-Cheek and Callum Hudson-Odoi would both have been included had they not succumbed to serious achilles tendon injuries, while Aaron Wan-Bissaka and James Maddison will play for the Under-21s in the European Championship.
