Blackburn Rovers boss Sam Allardyce blamed a defensive 'mess up' for Saturday's 1-0 defeat at Stoke City.
Matthew Etherington capitalised on defensive hesitation to feed Jonathan Walters and his strike settled a hard-fought encounter at the Britannia Stadium.
"The biggest frustration for me is the goal that we conceded here today," said Allardyce.
"It was such an easy defensive position to defend. We don't often see our central defenders mess it up like that to let what was a nothing situation develop into what was then a goalscoring situation which they took and it ended up being the winning goal.
"It is very frustrating to concede that type of goal at that particular time of the game.
"Goals are always difficult for us to come by, we know that, but we have scored in every game and if we had kept that going it would have gotten us a 1-1, but it hasn't happened.
"Our deficiencies defensively have made it so easy for them to nip through and score, bog standard basic defending has let us down.
"We went the goal down, we changed the system we went to three at the back and switched to a 3-4-3. But we huffed and puffed really without creating a chance."Subscribe to Football FanCast News Headlines by Email
