The third of a quick flurry came six minutes on, when Sekou Kone won possession, as he did many times on the night. He teed up Biancheri, who repaid the favour as he turned from scorer into provider with a well-weighted pass to Mantato, who had assisted the opener. The 17-year-old winger faced up his man, gave him the eyes and finished clinically with his left.
And there were still more to come before the break. Tyler Fletcher, drifting out to the right-wing, set this one up with a fizzing ball towards his brother, Jack. He finished first-time with his left, as he did again just three minutes later when Tyler pulled another back.
West Brom showed resilience after the break to fight in the early stages and regain a foothold in the game. That resilience earned a goal after 63 minutes, when Harry Whitwell earned and converted a penalty.
