Following a £9m move to Tottenham this summer, Jack Clarke immediately returned to Elland Road on a year-long loan in order to continue receiving regular first-team minutes.
The 18-year-old winger had a breakthrough season under Marcelo Bielsa and has revenge on his mind after Leeds ended their season in the Championship play-offs.
“It’s been probably the biggest moment of my career so far,” said Clarke.
“Making the decision to step away from the club after so long but it’s something I feel that was right for me and I was ready for it.
“Obviously there was always a plan to move on from Leeds eventually but I’d have much preferred it if we’d have gone up last year.
“It wasn’t a matter of where I would be playing. It was a matter of not feeling like I deserved to go after the way we finished the season. I felt like it wasn’t right for me to go.
“I feel like we’ve got a job to do. We feel like we let a lot of people down last season and we’ve got to put it right this year.
“It would mean everything to me to get this club back to the Premier League. It would be a childhood dream.
“Last year it was obviously a lot easier being an unknown prospect with people not knowing how I play. This year everyone knows what I’m about and what I like to do.
“It will obviously make things a lot more difficult but I’ll have to find ways to get around it.”
Clarke was awfully impressive in his first season of professional football, registering two goals and two assists in 25 competitive appearances.
