However, two minutes later Chelsea’s day started to take a turn for the worse when Thiago was shown a second yellow for a rash challenge on Okay Yokuslu.That was followed by a horror show in first-half stoppage time as Pereira took centre stage. The Brazilian’s first effort was a cute finish over Edouard Mendy before he finished off a gorgeous movie with a low strike between three defenders. In between those goals, Matt Phillips produced a strike that came off the woodwork.West Brom then went for the jugular as substitute Robinson made it 3-1 with a sensational side-foot volley before Mbaye Diagne finished off a sweet move with an even sweeter strike.England midfielder Mason Mount brought on at half-time, tapped in to reduce the deficit but the Baggies resisted other Chelsea threats before Robinson capped off a great day for the visitors with a clipped finish.
