Crystal Palace defender Mamadou Sakho is launching legal action against the World Anti-Doping Agency.

The Liverpool Echo says Sakho is suing for £13million - claiming a drug-test 'blunder' torpedoed his career at Liverpool.

Sakho, 29, was suspended from football in April 2016 after testing positive for a fat-burning substance following a Europa League tie against Manchester Utd.

The provisional 30-day suspension meant the France international missed out on Liverpool's Europa League Final defeat to Sevilla and, he claims, cost him a team place at the Euro 2016 tournament, London's High Court heard.

He was eventually cleared in disciplinary proceedings before UEFA, with the body finding that the substance - higenamine - was not actually on the banned list.

The Crystal Palace defender is now suing for £13m, with his lawyers arguing that his earnings as a player and the worth of his personal brand have been reduced by his move away from Liverpool.
