Tottenham boss Jose Mourinho has made Diego Costa his transfer priority ahead of the January transfer window.

That is according to Spanish outlet La Razon, which means Arsenal may have to enter a bidding war with their north London rivals next month for Costa.

The star striker left Atletico Madrid on Tuesday after both sides agreed to terminate his contract.

The Gunners and Spurs may face some competition from Wolves, who are also lining up a bid.

However, they will be pleased to know that Atleti have taken steps in order to make sure the Spain international doesn’t join another La Liga club and therefore crashing Real Madrid, Barcelona and Sevilla’s hopes of signing him
