Leicester City are being urged to accelerate new contract upgrades for their title winners.
The Sun says there is concern within the camp that important members of last season's title-winning squad are being left behind in the salary stakes — and that there seems no rush to sort the issue.
Skipper Wes Morgan, England midfielder Danny Drinkwater and Marc Albrighton earn less than a third of some team-mates.
Although morale remains high, Foxes' Thai chiefs risk upsetting the 'band-of-brothers' spirit Vardy and Drinkwater showed in their title celebrations, if some players sense their contract talks have been put on the back burner.
