For 20 minutes or so after that strike, Chelsea looked a force. Neto, in particular, was excellent, his pace and movement troubling the cumbersome Tyrone Mings and Ezri Konsa. For the opener, he interpreted his new role to terrific effect, curving his run from a central position to stay onside and then collecting on the more familiar right flank. He breezed beyond Ian Maatsen, who moved between these clubs last summer, and then delivered his cross perfectly between Mings and Emiliano Martinez. Fernandez could not miss.
