The Whites remain determined to keep hold of their key assets, however.
The report claims that Leeds owner Massimo Cellino is unwilling to sell the £8 million-rated midfielder and suggests that Newcastle will need to revive their interest in January, if they hope to secure a deal for the promising talent.
The 20-year old is one of a number of highly-rated youngsters to emerge from the Whites' renowned Thorp Arch academy in recent seasons, and Leeds’ reluctance to do business is understandable.
Uwe Rosler’s side are as well positioned to push for promotion out of the Championship this season as they have been for some time, and keeping the likes of Alex Mowatt at Elland Road is vital to that quest.
Newcastle, on the other hand, have had a busy summer of recruitment, but central midfield remains an area that they could do with reinforcing.
Georginio Wijnaldum’s arrival was a fantastic piece of business, but Cheick Tiote’s indifferent form means there is a lack of depth beyond Jack Colback and Vurnon Anita.
A young talent of the ilk of Mowatt would be ideal as Steve McClaren looks to build long-term, but any potential move looks like being firmly on ice for the time being.
