UWE Rosler believes Burton Albion raised their game to knock his Wigan Athletic side out of the League Cup on Tuesday night.
The Latics, who just over a year ago were a top flight side and FA Cup winners, were left reeling after the Brewers pulled off a mighty upset at the Pirelli Stadium.
It was a much-changed Latics side, but it still contained the likes of World Cup star Roger Espinoza, and NINE ex-Premier League players in James Tavernier, Ivan Ramis, Shaun Maloney, Leon Barnett, Ali Al-Habsi, Frazer Fyvie, Marc-Antoine Fortune, Martyn Waghorn and Grant Holt.
"With the team we put out we felt we had enough strength in depth to win the game," said former Manchester City and East Germany striker Rosler.
"But you need to put in a better performance than that when you are playing in the cup in England.
"We know the lower league teams raise their standards, and if you are not going flat out for 90 minutes, then you get hurt. We got hurt."
Wigan took the lead against the run of play, when Fortune was afforded too much space in the penalty area to fire home from a tight angle in the 27th minute.
It seemed as though that goal might be the signal for the Championship side to step up a gear, but instead they continued to allow Burton onto them, and the hosts equalised on the stroke of half-time through Dominic Knowles.
And things went from bad to worse for Rosler seven minutes after the break as Stuart Beavon fired home a deserved winner.
"It took us 15 minutes to get going, but after that I thought we took over the game and controlled it well," he said.
"We started to pass the ball with better tempo, and got our goal, but then we invited them onto us and made a catastrophic mistake to let them back into the game.
"I think for the team we had out there and the experience, we'd have liked a bit more character, determination and a will to win – we had to be more decisive in both boxes."
