The Swede was named by the Potters boss as the culprit after an incident in the tunnel at the end of the game resulted in the glass of a framed picture of the stadium being destroyed.

"Olsson smashed some memorabilia and that is very disappointing when it happens," he said.

"If you can't control yourself by not smashing someone else's property because someone refuses to shake your hand that is not an excuse.

"That has been paid for by this club and he has no right to break things like that."

West Brom boss Roy Hodgson tried to play down the incident, preferring to focus on the way his side fought back with a late equaliser for the second match running from Carlos Vela.

"There was a slight contretemps at the end of the game with the player being upset with one of their players not wanting to shake hands and he was a bit emotional," he said.

"I am pretty certain that a team that plays with so much heart and determination as Stoke will probably forgive us for breaking a picture.

"We will happily pay for it but I hope it will not take the gloss of what I think was a very good performance.

"I thought we did enough to get all three points.

"After the way we went 1-0 down from a corner - which is not unusual here - I was very pleased with the response of the players.

"I thought they not only kept going but they took over the game for large periods and we created some good opportunities and fortunately one of them counted.

"There were a couple of other occasions when we could have maybe got the winner but let's not be too greedy, let's be pleased that we have at least got a good point here."

Rory Delap had headed his side in front in the 53rd minute from Jermaine Pennant's corner but Vela snatched a point with a controversial equaliser as he appeared to be offside from Steven Reid's cross three minutes from time.

There were a lot of bodies in there and I couldn't say whether it was or not but if we did get some good fortune I would say you have to work very hard to get that," said Hodgson.

Pulis was certain the goal should not have stood.

"It is offside. It is a very poor decision by a linesman who is looking straight at it," he said.

The draw was enough to lift West Brom out of the bottom three, one point above the relegation zone.
