The Brazilian-born ace has quickly emerged as one of European football’s most prolific goalscorers, alerting a host of the continent’s top clubs in the process.
Arsenal have been among the chasing pack for some time, and are ready to launch a mega money move in the coming weeks to secure his signature.
With Olivier Giroud suffering with fitness issues and back-up man Nicklas Bendtner also on the sidelines, Arsene Wenger is desperate to secure a top class front-man.
Costa is seen as the ideal man to fire the Gunners to the Premier League title, with his 19 goals in 17 La Liga outings this season proving his credentials in front of goal.
Atletico themselves are far from keen to sell this month, but Wenger is ready to take the decision out of their hands by triggering the marksman’s release clause with a £32m swoop.
Chelsea are also interested in Costa, but it is thought that Blues will not be making big money moves during the current window unless players are sold first, leaving the door open for Arsenal.
