United are in a dispute with the Londoners over the two players who are officially only on trial at Stamford Bridge.
The dispute hinges around the amount of compensation between the two clubs for the players, which will be set by a tribunal.
According to the Daily Telegraph, the FA yesterday issued a letter detailing the players that will feature for England's U-16 side in an international tournament in France next month.
The letter includes both players in the squad, but their named club is Chelsea and not Leeds United.
Technically the players are in limbo, with United claiming that Chelsea made an illegal approach for them.
This letter will only serve to cloud the issue further which could end in a messy tribunal that could have been avoided.
