Try and guess which Atletico Madrid centre-forward made the following statement, as per Mark Redding at The Guardian: "I have three more years on my contract and next season I am still going to be here. I am very happy both in Spain and at Atletico."
It was Jimmy Floyd Hasselbaink in March 2000.
Wait, didn't he join Chelsea that same year? Yep (Atleti going down sped up the process).
Atleti manager Diego Simeone won't want Diego Costa to leave, as the club are level on points with Barcelona in La Liga, but the club's management have a history of selling their most valuable assets: Christian Vieri, David de Gea, Radamel Falcao, Fernando Torres, Sergio Aguero, et al.
Costa is represented by Gestifute, Jorge Mendes' agency. Who is the agent of Chelsea manager Jose Mourinho? Mendes.
According to Oliver Kay and George Caulkin at The Times (subscription required), Atleti and Chelsea have begun talks over Costa's transfer: "Chelsea are firm favourites to sign the 25-year-old in a deal that could involve Thibault Courtois, their outstanding 21-year-old goalkeeper, joining Atletico on a permanent basis."
So you tend to believe it is a matter of when, not if, Costa leaves.
Say he leaves in this window, who could Atleti replace him with?
