The winger said: “It’s been a bit stop-start, the last season I had up there. My first season in the Premier League, [it was] difficult with the club, and what was going on, the change of managers. So I just want to get back to playing football now.”
Buckley signed for Sunderland last summer, agreeing the transfer when Gus Poyet was in charge of the Black Cats.
Poyet was a big fan of the winger, having coached him at Brighton in the second tier, and used him frequently when he was in charge.
However, Poyet lost his job through the last campaign, and Buckley’s place in the side came under threat due to Dick Advocaat being named head coach.
It was clear that Advocaat was not keen on the 25-year-old, and after a busy summer on Wearside, Buckley had failed to make a single appearance for the side this season. He was relegated to the Under-21’s, and was not even named in a single matchday squad - for either Premier League or League Cup action.
Buckley has now left the Stadium of Light, agreeing an emergency loan with Leeds that runs until January 2. Leeds could then extend the deal to the end of the season, if they so wish, and it is hard to imagine Buckley would want to return to Sunderland considering his lack of football.
