Don't underestimate Senegal the way Deschamps did with Tunisia and France ended up losing with 1 goal. From now on you don't have a second chance, it is whether you qualify or you are out! Rotating his players when he is leading comfortably is a thing and risking a whole game due to miscalculation is another thing.
France will play vs Poland next and I think they took the lesson the hard way.
Senegal will be a tough game for England. Both teams have never played each other before. If Maguire has a good game and can keep Senegal from scoring, England should win.
