Arsenal are reportedly closely monitoring Diego Costa's situation at Atletico Madrid with Mikel Arteta keen to land the former Chelsea striker next month.
Costa's contract in the Spanish capital is up as of June 2021 but he is said to have instructed the Atletico hierarchy to terminate it six months early, according to reports in Spain.
AS Diario report that Atletico do not want to sell to a direct rival and with Arsenal not participating in the Champions League, interest in a move to the Emirates Stadium could suit all parties.
