Diego Costa has been speaking about his relationship with Real Madrid icon Sergio Ramos.
Costa has been the subject of intense rumours in the Premier League because his buy-out clause of £32 million makes him an extremely attractive proposition to both London based sides.
Arsenal need a forward to come in as back up and competition to Olivier Giroud while Chelsea have been lacking a prolific centre forward throughout the season.
However, should Carlo Ancelotti decide he needs a star striker in his team this summer, Los Blancos may just hold an advantage in the race to get him.
“We get on better and better. If I have to hit him, I hit him; if he has to hit me, he hits me. But all of that stays on the pitch,” Costa told AS in the build up to the game.
They would be extremely reluctant to sell to their city rivals, which brings the London clubs back into play.
Football has been laced with examples of rival clubs selling key players to each other such as when Luis Figo went from Barcelona to Real Madrid and more recently with Arsenal selling Robin Van Persie to Manchester United.
It’s not impossible Real Madrid could go after Costa following the World Cup but Arsenal and Chelsea may still get a chance to pounce.
