There was an interview with Sarr the other day where he discussed Ramadan. Hopefully he'll be feeling better this week after Eid. Link doesn't work, but it's called "Pape on Ramadan and making a Ketupat" on Facebook. It's in French but it has subtitles. He sounds like he may have benefited from having somebody to help him through it. Still only 21, but he's been so consistent before this match.
