Kilman has just made a deadline day move to newly-promoted Premier League outfit Wolves, which strangely could bring an abrupt end to his thriving international career.
Speaking after his inter-sport move - signing for the Molineux outfit's academy on a two-year contract - Kilman has admitted he may have to call time on his futsal career to achieve his lofty ambitions.
"In all honesty, I don't think I'll have any time to do futsal now because I'll be training with Wolves every day," Kilman told 'The Set Pieces'.
"I want to try to organise something so I can still play for England, but it's difficult and I'm not sure it'll happen. Of course I'm going to be upset if that does happen, but it's a risk I have to take to become a professional footballer."

Futsal is less common in England in comparison to the rest of the world. Futsal is played on a hard court, smaller than a football pitch and mainly indoors - however is not as popular as in South America.
He added: "When I was 18 and first in the England futsal team, I was definitely considering going abroad to become professional.
"Football maybe wasn't going as well for me and wasn't heading anywhere, so I was considering it. I was playing for Maidenhead's youth team and slowly broke through, but when I did get into the first team, I was sent on loan two leagues below. It was difficult and a long process.
'It was a bit physical [at Marlow] and, while it was enjoyable, I was starting to wonder where my football career was going to go. That's why I was even more willing to play futsal.'
