Chelsea's move to land striker Mauro Icardi could be in doubt after Atletico Madrid made a move to sign the forward, according to reports in Italy.
The Spanish giants are hoping to use their negotiations with Inter over midfielder Mario Suarez to get one over on the Blues by getting their Italian rivals to agree to a 'first refusal' clause..
Chelsea are reportedly eyeing a move for Icardi as they hunt for options up front for next season. At 36, this is likely to be Drogba's last season at Stamford Bridge, and boss Jose Mourinho is on the lookout for a third striker next to Diego Costa and Loic Remy.
Reports this weekend have claimed that both Chelsea and Liverpool are interested, while Inter Milan have conceded they may have to sell if they miss out on Champions League qualification.
Sporting director Marco Fassone said: "January is no time to make player sales, but at the end of the season it could certainly happen. Without the Champions League, some sales may be inevitable."
However Atletico Madrid may throw a spanner in the works as talks over Suarez continue. According to Italian newspaper Gazzetta dello Sport, the Spanish champions will agree to the sale of the defensive midfielder and ask for the first option on Icardi should he be sold in the summer.
As things stand, Inter are said to have offered a €2 million loan fee plus €11 million to make the move permanent. Atletico Madrid may not find that offer particularly favourable, but the inclusion of a clause for Icardi could make the difference.
That would prove to be a major problem for Chelsea as Icardi is likely to be keen on working with countryman Diego Simeone at the Vicente Calderon next season if he does move.
Potential alternatives for Chelsea include Roma's Mattia Destro and Real Madrid youngster Jese.
