Chelsea, centre-forward Diego Costa, has been heavily linked with an exit from Stamford Bridge in the recent months and La Liga giants Atletico Madrid who have finished as a Champions League runner-ups are reportedly growing confident to re-sign Spaniard finally. Earlier today the Spanish club have confirmed the Kevin Gameiro, but they still want to make £40million move for Diego Costa. The 27-year-old star has had a mixed time in his two years at Stamford Bridge and believed that he is keen on to leave the club and join his former team. Spain international forward is already believed to be missing his first game in the Premier League due to injury problems, and this may force Antonio Conte to increase interest for Romelu Lukaku.
