Kane's da is Irish but he always wanted to play for England, the other 2 played for Ireland up to u21 level, can't blame them declaring for England though , win some lose some.
Yeah those are the details but all born and raised in England so should be playing for England as far as I'm concerned. Of course, everyone should be free to choose what their heart, or head, tells them.
Bringing a QPR player as your main striker is the least #elite thing that's ever happened at the Euros.
A case in point, Liam Delap, his dad played for Ireland, he was born in England and declared for them, thought of highly, pity but that's the way it is.
