According to reports, Tottenham Hotspur boss Jose Mourinho is keen on signing free agent Diego Costa in January.
Costa is now a free agent following his release from Atletico Madrid.
La Razon claim Spurs are in the race for Costa and Mourinho is desperate for a reunion with his former striker.
Mourinho brought Costa to Stamford Bridge in the summer of 2014 after he fired Atletico to the La Liga title and Champions League final.
He helped the Blues win the Premier League in his first season in west London and was a champion again in 2017 under Antonio Conte.
