Nice will not consider selling Arsenal, Manchester City and Liverpool target Dalbert unless somebody stumps up his £26.3million release clause.
The trio of Premier League sides are on a list of clubs who were impressed by the versatile 23-year-old, who can play at both left-back or on the wing, during his first season in France.
Following his switch from Vitoria Guimaraes last summer, Dalbert impressed with 33 Ligue 1 starts last term.
It has been suggested that Nice would be ready to sell for around £12m this summer but now, according to Nice-Matin, he will not be sold for under his release clause.
