Chelsea striker Alvaro Morata sparked ire from Barcelona fans at Camp Nou last night for gesturing at them with his genitals.
The former Real Madrid forward came on 67 minutes into the decisive last-16 Champions League encounter and was subjected to repeated chants from the home crowd, including "Madridistas, sons of bitches" and "Morata, you are bad".
The 25-year-old was then caught on camera offering a response to the taunts.
Spanish journalists called for Morata to be disciplined by the Blues for his gesture, with Jota Jordi of El Chiringuito TV saying: "Morata's gesture looks intentional. I hope he'll be punished."
