27-year-old Diego Costa's message on Instagram caused doubts about the Spaniard's future at London's Chelsea club. Since arriving in London in 2014, D. Costa has been linked for some time with a return to Madrid's Atletico. This morning, Chelsea played a friendly match against Liverpool. They won after Gary Cahill scored a goal with his head. D. Costa did not play in this game, but after the match, he posed with his teammates in the locker room and wrote: "Thank you very much for all my friends!!!" This mysterious post sparked speculation about the footballer's future. Within Chelsea's ranks, the striker has played 78 matches and scored 37 goals.
