Mathieu Debuchy was sent off as Saido Berahino’s late penalty earned West Brom their first win in 10 league games at the Hawthorns.

The French right-back was given a straight red card for a two-footed lunge at Claudio Yacob and from then on there only looked like one winner as the home side pressured.

Alan Pardew made one change from the side that were edged out by Arsenal on Saturday, with Shola Ameobi coming in for Vurnon Anita. That meant the Magpies went with two up front and it ensured they started brighter.

Newcastle were comfortable in possession but unable to find a way through, thanks to a combination of the driving rain and stubborn Baggies defence.

At the other end, the home side were always a threat through the lively Morgan Amalfitano. The French winger – whose brother Romain is a Newcastle player – created a pair of notable chances in the first half that deserved better finishes.

The on-loan playmaker first crossed for Chris Brunt but the Northern Ireland international fired wide, before controversial striker Nicolas Anelka lifted an effort over the bar after being found by Amalfitano.

Yohan Cabaye had Newcastle’s best chance of the half but couldn’t test Ben Foster from 10 yards.

Baggies temporary manager Keith Downing clearly fancied his sides’ chances of winning the match and introduced England under 21 striker Berahino in place of injured right-back Billy Jones at half-time.

The youngster’s pace immediately caused Newcastle problems as his willing running tested Fabricio Coloccini and Mike Williamson. The latter denied the striker on one occasion with a brave block from a powerful effort.

Despite Berahino’s intent, the game changed when Debuchy was dismissed. The right-back was guilty of an ugly lunge at Yacob and despite not making much contact with the player, the two-footed nature of the tackle was enough to convince Lee Mason to show the red.

It got worse for Newcastle when captain Coloccini was withdrawn with an injury and replaced by Mapou Yanga-Mbiwa with over 25 minutes remaining. For the remainder, there only looked like one winner as the home side came forward constantly.

But it took until three minutes from time for the breakthrough to come, when substitute Matej Vydra skipped around Tim Krul and was clipped. Mason pointed to the spot and Berahino was trusted with the spot kick, which he sent low past Krul to earn West Brom the points.
