Slaven Bilić hailed the “complete performance” from his team which brought a third successive away win in the SkyBet Championship.
The brilliant Baggies overcame Bristol City 3-0, with two Hal Robson-Kanu goals and another from Callum Robinson at Ashton Gate.
It sparked jubilant celebrations from a delighted 3,000 following army of Albion fans and strengthened the Baggies grip at the top of the table.
“I must say this was a complete performance,” said Slaven afterwards. “I thought for the first 15 minutes there was not much fluidity to the game but then we scored and after that we were in control.
“We were always pressing, pressing and winning the ball high up the pitch. We had opportunities to score more goals I think but to come here to one of your rivals and achieve this score, which was deserved, is a complete performance. In defence, all over the pitch, a complete performance.”
Albion’s only setback in the game was a red card shown to Romaine Sawyers after he reacted to a challenge from his old Walsall team mate Jamie Paterson with Albion leading 2-0.
That was in the 77th minute but was immediately followed by Robson-Kanu’s superb third as he chased down a mistake Ashley Williams and lashed home an fierce left-foot shot from a narrow angle.
“The third goal is very important to us,” Slaven added. “Make no mistake, without that they would have made us suffer. There were 15 minutes or so left and with 10 men they would have had a big lift psychologically.
“But the third goal killed them - and it was quite a goal.
“For me, Romaine’s incident is not a red card. I know what the pictures will show but anyone who knows Romaine will know that there was not any malice in his reaction. For him to miss games now because of that is wrong in my opinion.”
