Radamel Falcao has signed with Chelsea and will join the club for their North American preseason tour.

The deal is believed to be a one-year loan from his French club, Monaco, with an option to make the move permanent next summer.

Agreement was eventually reached late last month, with Chelsea expected to pay the striker nearer £180,000 a week with a loan fee negotiated at around £4 million for his services.

Once one of the most feared strikers in the world, Falcao has endured a wretched time since rupturing his cruciate ligament in a French Cup tie 19 months ago.
