Barcelona coach Ernesto Valverde has professed his admiration for transfer target Antoine Griezmann but called for respect to be shown to Atletico Madrid.
Speaking over the weekend, Barca president Josep Maria Bartomeu revealed he had met with the player's agent and also held unspecified talks with Atleti president Enrique Cerezo.
The 27-year-old has long been linked with a move to the Liga champions and is expected to clarify his future prior to the World Cup.
Valverde, though, believes the France star should be left to concentrate on the Europa League final against Marseille next week.
