Tony Pulis believes his players were distracted before yesterday's 4-1 defeat to Queens Park Rangers.
Albion were 3-0 down at half time after poor defending allowed struggling Rangers to get a huge foothold in the game.
Substitute Victor Anichebe pulled a goal back for Albion before Joey Barton scored a late fourth for the visitors.
"We powder-puffed our way through 45 minutes of Premier League football, which you can't do," Pulis said.
"Brownie (Ideye) missed a good chance before they score.
"We should have dealt better with their first goal. The second goal was from a set play. Zamora scored a great third goal and the fourth goal shouldn't have scored because Charlie Austin tripped Gareth McAuley. That was a poor decision by the referee.
"There are a lot of things that go through footballers' minds. Getting to 33 points...people read social networks, social media and listen to the press who say they're safe. The one thing for sure is that if you're not on it 100 per cent you will get a rude awakening. And we that's exactly what happened.
"The players have to be full out. And we weren't, especially in the first half."
