If Edouard Mendy was hoping to use the Qatar World Cup to escape the negativity at Chelsea and rediscover some confidence, his opening performance against the Netherlands only increased the harsh spotlight.
Caught in no man's land for Cody Gakpo's header to give Holland the lead in the final 10 minutes was scrutinised, then the error was compounded by a fumbled stop to a Memphis Depay effort heading into the path of Davy Klaassen to make it 2-0.
The two errors dearly cost Senegal a valuable point in Group A in what was a pretty forgettable contest until the final 10 minutes. For Chelsea and Graham Potter, the concerns over Mendy will run much deeper.
