London (AFP) - West Bromwich Albion manager Tony Pulis ended speculation about his future on Friday as he signed a one-year contract extension with the Premier League club.

Albion are under new Chinese ownership and it had been suggested Pulis might part ways with the Baggies after expressing his displeasure at the lack of quality signings in the last transfer window.

Pulis was reported to have clashed with chairman John Williams over the failure to land his targets, while some fans are unhappy with his brand of conversative football.

But the 58-year-old is set to stay at the Hawthorns until 2018 after agreeing with Albion owner Guochuan Laito to extend his previous deal, which was due to expire at the end of this season.

"This is a time of great change at Albion and when that happens you need continuity," Pulis told Albion's website.

"As I have said from the outset, I want to build things here and play my part in improving the club. You cannot do these things overnight but I do believe, step by step, we are making advances.

"I think the bulk of our fans understand the process we embarked upon under the shadow of relegation less than two years ago."

Former Stoke boss Pulis, who has been with Albion since January last year, has overseen just two wins in nine league games this season and his team are only three points above the relegation zone.
