Jayson Molumby is back in business – after a 15-month absence.

The Irish midfielder played the first half of Albion under-23s’ Premier League Two match at Manchester City tonight.

His comeback was part of a great night for the young Seagulls at City’s academy stadium.

Danny Cashman’s first half goal secured a 1-0 win – and the league double over City this season.

Molumby has suffered knee problems to put his blossoming career on hold after making two Carabao Cup appearances for the senior side last season.

Before the setbacks, he had also progressed through the age groups with the Republic of Ireland as a contemporary of Declan Rice, the West Ham star who this week pledged his international allegiance to England.

Molumby tweeted back in early August: “New knee for my 19th birthday. Second op in under a year hopeful this one sorts the problem looking forward to getting back.”

Albion made a dream start by going ahead in the 13th minute.

Alex Cochrane got on the ball during a rapid attack, played a pass and Cashman produced a calm finish into the bottom corner.

Albion looked good on the ball in the first half but City had their chances to level.

Owen Moore did well to block a shot and Tom McGill made a super save late in the first period.

McGill held a dipping effort on 66 minutes as Albion had to soak up a lot of pressure.

Then the keeper stole the show in the late stages with two superb saves from Spanish midfielder Adrian Bernabe to secure the points.
