Carlos Corberan hailed the impact of West Brom’s January recruitment drive as two new signings scored in his side’s 2-0 victory over Cardiff.

Winger Mikey Johnston, who arrived in the window on loan from Celtic, opened the scoring after just 30 seconds before Bristol City loanee Andreas Weimann emerged from the bench to secure the points in the 80th minute.

West Brom’s fifth win on the spin on home soil was significantly influenced by the new recruits, who have turned the heat up on Corberan’s pre-existing attacking options in competing for places – but that is something the Spaniard now relishes when selecting his team.

“It’s necessary to have these options,” Corberan said. “It’s something key, because if you don’t rotate the players, at the end you have more injuries.

“For us, as a club, it was necessary for us to add more attacking options, because we needed to increase the options we had. Right now, we’re using the players, because it’s necessary to have that impact from the bench.

“Our players now know that we have now good options. They believe in the team-mates they have. Our attacking players know that if they’re not at 100 per cent, we have others who will be. They understand it’s a strength we have and must use.

“It can never be a problem, to have two or three players competing in every position – now we have those alternatives.”

West Brom effectively began the match a goal ahead when Tom Fellows crossed for fellow winger Johnston, who stroked the ball home after just 30 seconds.

Cardiff tried to draw level prior to half-time, but Josh Wilson-Esbrand did not sufficiently worry Alex Palmer with his shot from distance.

Palmer would have been concerned, though, when Kion Etete met Aaron Ramsey’s header at the back post, and West Brom were thankful when the centre forward skewed his attempt over the bar from close range.

With it went the visitors’ most significant opening of the evening, and they were punished shortly afterwards when Jed Wallace collected a through-ball on the right and fired a cross in for Weimann to turn home.

For Cardiff manager Erol Bulut, there was only regret that his side did not take their one significant opportunity to equalise when the chance came their way.

“It’s difficult when you concede a goal in the first minute against West Brom, who are at home, with quality players,” he said.

“It’s not easy but we pushed really hard, especially in the second half, we had chances to score and make it 1-1, with Kion and with Ramsey.

“If you don’t score, it’s normal that at the end they get the second one, because we were pushing to get the second one.

“Opponents, when they get those chances they are scoring and we are not scoring. This is the difference. We have the chances, but we are not scoring.”
