Tony Pulis, the manager of West Bromwich Albion, Chelsea's next opponents, was at Stamford Bridge for this. What did he learn?
Probably, that the most he and his team can do on Friday night, is delay the return of the Premier League trophy to Chelsea by a few days, at best. They are unlikely to inflict permanent damage, to blow anything wide open, to turn the title on its head. Little they can do will give hope that there is to be a final twist.
The trip to West Brom is Chelsea's last away match of the season and Chelsea demonstrated against Middlesbrough what they can do to weak teams, at home.
