Sakho's 'drug' not on banned list

France international Mamadou Sakho was suspended last season for taking a substance that was not in fact on Wada's banned list, a Uefa report has confirmed.

The Liverpool defender, now on loan at Crystal Palace, was banned for 30 days after failing a drug test on March 17 and, as a result, missed the Europa League final and Euro 2016.

The Uefa report blames a communications breakdown between Wada and its laboratories in Cologne and Lausanne for the error.
