Former Atletico Madrid coach Gregorio Manzano fears his old club will struggle to keep Radamel Falcao.
The Colombian is a top target for Chelsea.
"Whoever bets on Falcao will not be disappointed, it is a safe bet even for Real Madrid and Barcelona," Manzano told COMRadio.
"Falcao will succeed at any club, as long as he is part of a good team. He really knows how to score goals."
