Jackson Martinez could lead Chinese Super League foreign exodus as players look for game time ahead of 2018 World Cup
New rules from CFA further limit overseas players mean those hopeful of being picked for Russia may need to move on to ensure regular action

Reports have emerged that Colombia international Jackson Martinez, who last played for champions Guangzhou Evergrande 14 months ago, may join Turkish Super League club Besiktas.
The South American missed the whole of the 2017 season after surgery on his left ankle and is eager to get first team soccer to enhance his chance of making the 2018 Russia World Cup finals squad for his country.
Besiktas, the reigning Turkish champions, are said to have been interested in Martinez since last year and their appearance in the Uefa Champions League round of 16 against Bayern Munich in February would be an added incentive to attract the player.
