Jack McKay says he jumped at the chance to join Leeds United from Doncaster Rovers along with brother Paul.
The 19-year-old twins switched to Leeds for an undisclosed fee on Monday, signing respective two-and-a-half year deals.
And striker Jack says he had no hesitation in making the move.
"It's a massive club," he told Leeds' official website.
"As soon as I found out that Leeds wanted to bring us me here, I said ‘yes’ straight away.
“We were both told on Monday morning that Leeds had come in for us and we were buzzing to hear it.
“I know there’s competition here with the young strikers, but that doesn’t really matter to me. I know that if I’m not the best then I won’t play. I have to be at my best
Paul added: “It’s a massive club and I’m delighted to have signed up.
“You look at the young players here recently – Sam Byram, Lewis Cook, Alex Mowatt – they’ve all broken into the first team and have become regular players.
“There’s definitely a pathway here for a young players like myself and my brother to kick on.
“To start with I think we will get games in the Under-21s and train with the first team when we can and then take it from there.
“It’s good having someone else in the family doing the same thing as you. It can help ease you into a new club."
Both players came through the youth system at Rovers and were handed their first senior contracts early in the 2014/15 season.
Centre half Paul played the full 120 minutes of the Johnstone's Paint Trophy clash with Burton Albion earlier this season - his only senior appearance for the club.
Striker Jack was an unused substitute on three occasions this season. He made one senior start for Rovers - at Notts County late last season - and three substitute appearances.
