Semi Ajayi scored his second Premier League goal of the season to help West Brom come from behind to stun rivals Wolves in a see-saw Black Country derby that saw Sam Allardyce claim a first win as Baggies boss.

The Super Eagles defender has been immense for the struggling Baggies especially away from home and finished off a header from Kyle Bartley’s flick on to draw West Brom level in the second half, providing the foundation for the Baggies stunning win at the Molineux.

The Foxes had recovered from conceding the opener from the spot in the eighth minute to lead at half time.

Matheus Perieira scored from the spot following Wily Boly’s foul on Callum Robinson but Fabio Silva and Boly replied to turn the tie in favour of the home side.

Ajayi, whose goal helped West Brom secure a point at Liverpool then levelled matters seven minutes the interval before Pereira beat Rui Patricio again from eight yards four minutes later following Conor Coady’s foul on Robinson to secure only the Baggies’ second win of the season.

It was also the time West Brom had scored three times away from home in the Premier League in almost seven years.

Despite the win, West Brom remain in the relegation zone but the manner of their win will provide fresh optimism about avoiding the drop.

The result extended a miserable run for Wolves, who since striker Raul Jimenez fractured his skull at Arsenal on 29 November have taken five points from nine games and slid down the table into 14th spot, with all the clubs below them having games in hand.
