Atletico Madrid boss Diego Simeone admits it will be "very difficult" to keep Chelsea and Manchester City target Radamel Falcao in the Spanish capital.
Falcao, 27, is arguably the most feared striker in the world following his exploits for Porto and Atletico.
The Colombian sensation has scored 136 goals in all competitions since moving to Europe from River Plate in 2009, with 64 of those coming since he joined Atletico at the start of last season.
City and Chelsea are both expected to strengthen their attacking options at the end of season in a bid to boost their domestic and European ambitions.
The former, who sold Mario Balotelli in January, could lose Edin Dzeko in the summer, while the latter desperately need an elite centre-forward to play in front of Eden Hazard and Juan Mata.
And both sides have received a boost after Simeone revealed Falcao is likely to be on his way.
"It will be very difficult to keep Falcao, but it would be a wonderful thing," he is quoted as saying on TuttoMercatoWeb.
