The discussion is pretty much done, but I don't understand why people defend Bouhanni.
When they come out of the final corner Matthews leaves Bouhannis wheel to pass him on the left. The moment he does that Bouhanni moves to the side of the road. Obviously aware that Matthews is about to pass him there. At first he leaves atleast a little bit of space for Matthews who isn't intimidated by Bouhanni's first move and keeps on moving up on the left. Then Bouhanni decided to close the gap completely.
It's so obvious. The first extreme line deviation is allready pretty bad, but that happens in a sprint, but the final closing the gap while Matthews is allready next to him is ridiculous.
I don't see any blame on Matthews for this who was allready with his front wheel next to Bouhannis rear wheel when Bouhanni moved to the side of the road.
