The bitterness between the two clubs in the aftermath of the Saido Berahino transfer has taken a bizarre turn after the Baggies' 1-0 win last weekend
Stoke City manager Mark Hughes has claimed his West Brom counterpart Tony Pulis phoned Ryan Shawcross to call him a "loser" after their match last weekend.
The Potters' 1-0 loss at the Hawthorns was played amid a bitter atmosphere, with the managers refusing to shake each other's hands at the final whistle and Saido Berahino loudly booed by his former fans.
The level of animosity developing has now taken another turn after Hughes told a press conference that Pulis left a message for Shawcross in which he apparently insulted the Stoke captain, who he previously managed during his spell at the Britannia Stadium.
