Leeds have been keen to hold on to Adams this summer despite being relegated from the Premier League last season.
However, he has had several suitors in the Premier League who have been keen to snare him away from the Whites in the ongoing transfer window.
The midfielder is now set to leave the Whites imminently with Chelsea now pushing to secure his signature in the coming hours.
It has been claimed that Chelsea have triggered his £20m buyout clause in his contract to push through with a deal to sign him.
With his release clause triggered, the midfielder is now ever closer to moving on from Leeds this summer.
It has been suggested that the US international is set to undergo a medical with Chelsea ahead of the transfer.
The Blues will have to register Adams by Friday noon if they want him in the squad against Liverpool at Stamford Bridge on Sunday.
