Journalist Joe Chapman was left impressed with Jayson Molumby's lively home debut after West Brom's narrow 1-0 win over Birmingham City.

The Lowdown: West Brom go top

The Baggies returned to Championship duties on Friday evening, resuming their title charge at the expense of Birmingham.

Karlan Grant's expertly-taken second-half strike was enough for Valerien Ismael's side get the better of Lee Bowyer's Blues, despite a less than perfect performance.

The Latest: Molumby impresses on home debut

West Brom struggled to click overall, but someone who did their future chances no harm was Molumby, who made his home debut after joining on loan from Brighton in the summer, coming on as a substitute after the break.

Taking to Twitter on Friday night, Chapman showed his appreciation for the 22-year-old in a positive five-word verdict:

"A word on Jayson Molumby. Home debut, in a derby match with things not going the way of WBA. Made an impact. Promising signs."

The Verdict: Promising early signs

As Chapman alludes to, Molumby has made an encouraging start to life at the Hawthorns, playing with the kind of intensity that will likely appeal to Ismael.

He made one tackle and won his only aerial duel when he came on and was 'buzzing around the place', according to Chapman in his post-match player ratings.

Molumby may not be a key starter as the season progresses but he has shown that he can be effective from the bench, with squad depth so vital in the gruelling Championship campaign.
