Diego Simeone says the opinion of Atletico Madrid fans should always be respected after some supporters protested against the proposed signing of Alvaro Morata.
The Spain striker has been tipped to join the La Liga club on an initial loan deal following Gonzalo Higuain's move to Chelsea from Juventus.
Atleti fans voiced their disapproval of a deal for the former Real Madrid man on Saturday, though, with chants of 'Less Morata and more Borja Garces' heard during the 2-0 league win over Getafe at the Wanda Metropolitano.
Garces is one of Atleti's most highly regarded youngsters, having been compared to fan favourite Fernando Torres after scoring on his league debut against Eibar in September.
