Leeds have addressed reports there is a clause in the teenager's contract.
The club suggest the reports in the Yorkshire Evening Post were published with 'damaging intentions' and have confirmed that there is no clause 'whatsoever' in the teenager's current terms.
Leeds posted the following statement on Thursday afternoon: "Leeds United would like to categorically deny reports that have emerged in the local press this morning regarding a supposed release clause in the contract of Lewis Cook.
"The claim by the Yorkshire Evening Post, which the club feels was published with damaging intentions, is entirely inaccurate and unfair reporting. No release clause whatsoever exists in the contract of the player in question."
How this would affect Cook's future remains to be seen. It certainly strengthens Leeds' hand compared to if there was a release clause for the midfielder.
But, should United continue to struggle, there not being a clause does not guarantee the playmaker remaining at Elland Road.
It would simply generate a greater fee should the player want to leave Leeds. That's certainly a preferable option to losing him for a set amount, however.
After losing 4-0 at Brighton on Monday night, Leeds host Bolton Wanderers on Saturday afternoon.
