Harry Redknapp described Saturday's loss against Wigan as a 'rare bad day' and admitted: "We just didn't get going."
Wigan proved a tough nut to crack defensively and then hit us with a counter-attack to snatch all three points in the 81st minute.
Ali Al-Habsi made two fine saves, one in each half, to deny Jermain Defoe and then Niko Kranjcar.
It looked like we might grab an equaliser in injury time but Younes Kaboul's header agonisingly sailed the wrong side of the post with Al-Habsi beaten.
"We started slowly, gave the ball away a couple of times early on and couldn't seem to snap out of it," said Harry.
"They closed us down, pressed us and the only spare man we had all the time was one of our centre-halves, so the ball kept going back to them.
"That kept happening because they didn't give us any space to play. It was difficult for us."
Harry immediately shrugged aside any suggestions of a 'hangover' following our midweek exploits to qualify for the group stages of the Champions League.
"Why should it be?" he responded. "You should come here full of confidence after winning 4-0 in the Champions League.
"You should feel fantastic, not have a hangover or feel lethargic. You should come out knowing that the crowd loved the way you played on Wednesday and really play, but credit to Wigan, they were athletic, closed us down and we didn't have the guile to break them down.
"It was disappointing on the back of a great week with the win at Stoke and then the Champions League on Wednesday.
"It was a rare bad day. We've not had many bad days at the club since I arrived, but that's how it goes. We prepared as normal, it just didn't go our way."
