Tony Mowbray’s unbeaten start to life as Birmingham boss continued with an impressive 2-1 win at Stoke.

Fulham loanee Jay Stansfield handed the visitors a dream opening when he fired in an eighth league goal of the season after 10 minutes.

The Potters, who were unbeaten since Steven Schumacher’s appointment last month, reacted positively but struggled to create clear chances.

Mowbray’s outfit began the second period in similar fashion to the first as Juninho Bacuna’s exquisite free-kick doubled their lead.

The home side teed up an intriguing finish to the tie when Jordan Thompson halved their arrears, but Blues held on for a crucial three points.

Stoke, who were unbeaten in five league games, started brightly and should have opened the scoring inside eight minutes.

John Ruddy parried a troubling Wouter Burger volley only as far as Bae Jun-ho, but the South Korea youth international could only fire the rebound into the side netting.

The hosts were immediately punished as Birmingham landed a sucker-punch on the counter through their leading marksman.

Koji Miyoshi’s through ball was latched on to by Stansfield, who shrugged off the challenge of Luke McNally to fire in an emphatic opener.

The Potters responded brightly to their early setback and should have levelled to cap off a frenetic first quarter of an hour.

Ryan Mmaee sprung the offside trap and raced through on goal, but his shot was saved well by the imposing Ruddy.

Then it was the turn of forward partner Andre Vidigal to go close, yet his guided effort dropped narrowly wide of the far post.

Only Exeter have scored fewer home league goals in the EFL than Stoke’s tally of 10 this season, and that wastefulness in the final third was on show again.

The hosts struggled to make their dominance count and Michael Rose spurned the chance of the half when he failed to convert from point-blank range.

At the opposite end, a bright Stansfield nearly notched his second of the afternoon before the interval, but he miscued his strike following a Daniel Iversen save.

The England Under-21 forward’s blushes were saved shortly after the restart thanks to a moment of brilliance courtesy of Bacuna.

The Curacao international stepped up from 25 yards and curled a delicious free-kick straight into the top corner beyond a helpless Iversen.

Again, Stoke rallied in their pursuit of a response with Jun-ho lifting an effort on to the crossbar and substitute Tyrese Campbell also going close.

The hosts’ persistence was eventually rewarded when Thompson bundled in his side’s first home league goal from open play since October 25.

But a late onslaught proved to be in vain for Schumacher’s side, who failed to repeat a 3-1 victory from the reverse fixture on Boxing Day.
