It was a hard-fought affair at Stamford Bridge which Pulis admits was a fairly strong performance from his Baggies, who sit eighth on the table.
“The goal’s disappointing because Gareth should have dealt with it,” said Pulis.
“I’m disappointed for them, because they’ve put so much into the game to then get beaten by that one mistake.
“I have no qualms about how hard they worked. Hopefully that honesty will set us up to achieve something in the rest of the season.”
