Paris Saint-Germain could compete with Chelsea for the signing of Atletico Madrid striker Diego Costa, [football] direct news understands.googletag.cmd.push(function() { googletag.display(“div-gpt-ad-1389116196215-0”); });The Ligue 1 giants look set to lose Edinson Cavani this summer, with the former Napoli forward reportedly unhappy with life at the Parc des Princes after only a few months at the club. With Cavani being linked with the likes of Manchester United and Real Madrid, PSG are keeping an eye out for possible replacements upfront, and look to have identified in-form Atletico man Costa as a good option. The 25-year-old has been one of the most prolific strikers in Europe this season, scoring 24 times in all competitions in just 26 appearances, attracting plenty of interest from Premier League clubs. Chelsea would appear to be his main suitors, though Arsenal have also been linked with him in recent months. Interest from PSG, however, could put Costa out of both clubs’ price range. Atletico have lost a number of big-name players in recent years, with another star striker Radamel Falcao making the lucrative move to Ligue 1 last summer with Monaco.
