Edouard Mendy carries the 'blind faith' of his Senegal boss Aliou Cisse and his teammates as the African champions attempt to pile more misery on hosts Qatar.
Chelsea goalkeeper Mendy was at fault for the first goal as his team lost 2-0 to Holland on Monday.
Now they go head to head with the home nation and Asian champions in Doha's Al Thumama Stadium on Friday, with the losers painfully aware they are unlikely to progress from Group A.
'Edouard doing very well, he has a steel resolve,' said Cisse.
