Wolves boss Mick McCarthy criticised the behaviour of West Brom midfielder Paul Scharner after the Baggies secured a 2-0 victory at the Hawthorns.
McCarthy claimed his players were upset because they felt Scharner had lifted his match shirt and displayed the contents of a T-shirt towards some of them, but Scharner defended his actions, insisting the T-shirt only contained a club logo and the words 'West Bromwich Albion'.
McCarthy said: "Scharner had something on his T-shirt and showed it to the lads over the other side (of the pitch). There is no need for it and maybe that upset the lads. You can lose but you don't need your nose rubbing in it."
He added: "If there were words said (between the players), it would have been because of that. He lifted up his shirt, there is no need for it.
"It's when you get responses. Take the mickey with the ball, that's the game. I get the hump with it."
But Scharner is adamant his actions were not meant to anger the Wolves players.
He said: "My kids gave me the T-shirt. They stuck a club logo on it and I was just showing it to the fans. That's all."
Wolves have now lost five games in a row as goals from skipper Chris Brunt and Peter Odemwingie secured Albion's first home win of the campaign.
McCarthy said: "I could say they were clinical as they had two good finishes and we didn't.
"We started well but being the best team for seven minutes is no good if you then concede. It could have been avoided. The second goal knocked the stuffing out of us. We had enough chances but we weren't clinical."
