From about the 10th minute onward, Chelsea's win over Arsenal was a far more substantial beatdown than the scoreline indicates. A week ago, Antonio Conte's crew felt that a combined two or more points from the trip to Anfield and the visit of the Gunners would be a decent outcome since, at worst, it would leave Chelsea six points clear. Instead, they're now nine clear at the top, with the lead over Arsenal stretched to 12 points.
Arsene Wenger felt that Marcos Alonso fouled Hector Bellerin on the opening goal ("100 percent," he said) but he was in a distinct minority.
