Sunderland extended their unbeaten run to 10 games but, as the ­smattering of gentle boos that greeted the final whistle testified, it was most certainly not a cause for celebration on Wearside.

Instead a fifth successive draw against highly efficient, if ­somewhat unambitious, opponents well practised at pinching ostensibly unlikely points led to Régis Le Bris’s early pacesetters slipping to third in the Championship. West Brom’s reward for the obduracy that so frustrated mildly disgruntled Stadium of Light season ticket holders was a drop to seventh in an increasingly ­fascinating second tier.

Carlos Corberán may soon have to decide if he wants to fill ­Leicester’s managerial vacancy but West Brom’s much coveted head coach cut his usual fully committed, often highly agitated, technical‑area figure as he watched the excellent Torbjørn Heggem frequently hold West Brom’s makeshift defence together. “It was a very difficult game,” Corberán said. “Sunderland had a lot more chances than us; we achieved one point with a lot of hard work and resilience.”

A sanguine Le Bris proved ­typically realistic. “The players and I are ­feeling disappointed,” he said. “We dominated and had four or five chances but West Brom defended well. We’re a young team and I’m very excited about our ability but we have to learn quickly.”

There was early upheaval when Corberán found himself forced into an unscheduled personnel revamp as Ousmane Diakité was injured in the warm‑up, necessitating his replacement by a not yet properly fit Kyle Bartley.

It proved a rare moment of minor drama as little else of note happened during the opening 45 ­minutes. Admittedly Josh Maja seemed keen to impress on his latest return to his old club but the nearest West Brom’s largely service‑starved leading scorer came to a goal was an early shot directed wide following his slick connection with a Tom Fellows cut‑back.

With Bartley, still nursing a knee problem and replaced by a midfielder, Uros Racic, at half-time, initially holding his own in an extremely well‑organised visiting backline, the majority of Sunderland’s shots came from outside the area.

Tellingly Wilson Isidor unleashed the sole first-half shot on target – a benign and easily saved deflected strike – as the home side’s promising approach play invariably fizzled out around the 18-yard line.

Long before half-time the sense that West Brom, in particular, were playing with the handbrake on ensured it had all turned distinctly flat. Small wonder Corberán’s team have only 11 points to show for their nine-game unbeaten run.

With two key promotion rivals in Sheffield United – who host Sunderland in an intriguing looking game at Bramall Lane on Friday night – and Burnley both winning, while latterly renascent Middles­brough and Leeds were preparing for games on Wednesday night, Le Bris’s players strove to reaffirm their automatic promotion credentials.

Yet despite winning a stream of corners they could never quite make the most of such set pieces. It might have been different had Maja still been wearing red and white stripes but no current Sunderland player could quite make the most of some promi­sing wing play from Patrick Roberts.

Granted, Isidor did deposit the ball in Alex Palmer’s net after meeting Luke O’Nien’s cross but the striker was fractionally offside. Significantly that close call came at the conclusion of a rare highlight, namely a gorgeous move involving Jobe Bellingham, Dan Neil, Roberts and Chris Rigg.

A little later Rigg was clearly onside and his shot seemed goalbound but Alex Mowatt’s fine 11th-hour block ensured the impasse endured. After that Roberts sent an angled shot whizzing inches wide, while Dan Ballard’s last-ditch clearance off the line denied Lewis Dobbin a counter-attacking goal but a winner remained stubbornly elusive.

“Bartley wasn’t fit to start and we ended up with a No 8 [Racic] ­playing centre-half,” Corberán said. “You can’t always win but all my players gave their best.”
