Premier League trio Liverpool, Chelsea and Arsenal are reportedly keeping tabs on Atletico Madrid star Diego Costa.
The 25-year-old, who attracted interest from Liverpool in the summer, has been in fine form in La Liga by netting 13 goals so far this season.
While Costa is said to be happy in Madrid, reports in Germany have claimed that the forward has a £20m release clause, sparking the interest of the Reds, Chelsea and Arsenal, according to The Express.
Borussia Dortmund are also said to be keen on Costa as they search for a new forward ahead of Robert Lewandowski's imminent departure.
