Atalanta director Luca Percassi is adamant Luis Muriel is not for sale.
The attacker is being with a move to the LaLiga this summer.
“All that's real is that Muriel is an extraordinary talent and we are holding on tight to him," Percassi told Bergamo TV.
“The objective for next season is without doubt to strengthen the squad so that we can be even more competitive."
The Colombia international has scored 22 goals with nine assists in 38 competitive matches for La Dea so far this season.
