The winger has become one of the hottest properties outside of the Premier League following his 18 goals for Leeds last season with Stoke, Fulham Newcastle, Wigan, Swansea and Queens Park Rangers all said to be interested.
The 23-year-old was expected to move on to a Premier League club this season with the Potters leading the chase but Gradel says he has no intention of quitting Elland Road.
“Leeds is a massive club. It is the best I have been at and to play at a club like this is a dream,” Gradel revealed. “I want to keep playing at this club for a long time to come.
“There are a lot of positives to be taken from last season and now we are ready to go again. We deserve to be in the Premier League.”
