Tottenham head coach Mauricio Pochettino admits Harry Kane may miss the start of next season if he plays for England at the European Under-21 Championships this summer.
Gareth Southgate names his provisional squad for the tournament in the Czech Republic on Wednesday and if Kane is included, it will leave the striker only 18 days to recuperate after Tottenham's postseason tour of Malaysia and Australia.
Spurs face Everton on Sunday in their final Premier League fixture of the season before the squad fly out on Monday to face a Malaysia XI in Kuala Lumpur on May 27 and Sydney FC three days later.
If Kane is called up by Southgate, he is likely to be left out of the England senior squad's fixtures against the Republic of Ireland and Slovenia at the start of June, and excused from an under-21 friendly against Belarus.
It would still, however, give Kane less than three weeks' break before the Young Lions' opening tournament match against Portugal on June 18.
England will play three group matches before a potential semifinal on June 27 and final three days later.
Pochettino has previously said Kane will need a month's holiday to recover from a campaign that will stretch to 53 appearances for club and country if he plays against Everton on Sunday.
A month's rest after the European Under-21 Championships would see Kane miss the majority of Tottenham's preseason training, which Pochettino sees as crucial to his team's high-tempo style of play, before the new league campaign begins on August 8.
"Could he miss the start of the season? Maybe," Pochettino said.
"But it is because of that I am sure the FA will take the right decision for Harry Kane and for England.
"I am happy if Harry is happy. In the end it is a decision for the FA, we need to wait for the FA's decision.
"If Harry asks me, I will say it is his decision. If you have the possibility to play in the under-21s it is always the player's decision.
"We can advise him but it is up to the FA and the player.
"The problem is there are different interests. We are a club in England and we need to be careful.
"The manager's decision in this case is to build the team and decide and pick different players.
"His decision and our interests are maybe different to the FA's. But we understand the decision will always be with the FA."
Kane has enjoyed a remarkable season at Tottenham, scoring 30 times in all competitions for his club, but the striker has been less prolific in recent weeks.
One goal in seven has led to suggestions the 21-year-old is suffering from fatigue.
"Harry is not tired," Pochettino added.
"The problem is when you play a lot of games in the Premier League and Europa League, you spend a lot of energy and it is not easy.
"He is not tired, it is about next season. We can see him in the future because for us he is a future number one in the senior England squad."
