The Tottenham striker has scored 29 goals in all competitions this season and the Chelsea defender believes he should play for Gareth Southgate's team in the Czech RepublicGary Cahill insists Harry Kane should play for England's Under-21 side at the European Championships in June, despite his call-up to the senior squad.
Tottenham striker Kane has been in stunning form in 2014-15, scoring 19 Premier League goals, and his rise to prominence was capped by last week's call-up to Roy Hodgson's Three Lions squad for the upcoming games against Lithuania and Italy.
However, Kane is also eligible for the Under-21s and Cahill believes he should answer the call if Gareth Southgate selects him for the tournament in the Czech Republic this summer, having himself featured for the side in the 2007 competition.
"When you're asked to play for England's seniors or the Under-21s you want to go and play," he said, "I'm sure he's [Kane] not different.
"When it comes to that time [when he might get the call-up] I'm sure he'll accept. He's had a taste of the seniors and there'll be more squads he'll be part of.
"It's important for us that the Under-21s do well at the Euros this summer. They have a good squad and their ultimate aim is the senior squad.
"I went to the Under-21s finals and it gives you experience as a player. It's good for the players' development."
Kane trained with the senior squad for the first time on Tuesday, and Cahill has been impressed by what he has seen thus far.
"[He's been] really good, I've played against him three times this season and he's a handful," he added.
"He's had a fantastic season. He can hold the ball up, run in behind, he has two good feet - so he's got all the attributes.
"To score a hat-trick before joining the squad is ideal. His confidence must be sky-high. He's still a young boy and the first time in the full squad all a bit daunting, but his confidence is sky-high."
