Atletico Madrid striker Radamel Falcao has some doubts about moving to Chelsea in the summer.

Spanish sources insist Falcao will sign for Chelsea at the end of the season after his representatives struck terms with Blues officials before Christmas.

However, the People says Falcao has big doubts about joining Chelsea due to Roman Abramovich's erratic decision making.

The Colombian is concerned about the instability of the club and how he can handle the regular manager sackings at Stamford Bridge.
