STRIKER Martyn Waghorn reckons Millwall need to go back to basics after their midweek thumping at St Andrew's.
The Lions went into the game full of confidence off the back of three straight wins, but the Blues romped to an emphatic 4-0 victory.
But whilst there were no positives to take on the night, Waghorn is confident Millwall will respond against Bournemouth on Saturday – as they did after their humiliating defeat to Derby County last month.
The Leicester City loanee said: "We can't dwell on it. After the Derby game, we put that to bed, came back flying and won three on the bounce. We've got winning performances in our locker and that's got to be our mindset.
"You think about a result like this for a day or so, but you have to get over it and work hard for Saturday.
"There were a lot of things that accumulated into a bad performance and result. We've got to take a hard look at ourselves individually and collectively.
"It was one of those freak performances where nothing goes right on the night. Whether that was because of the way we prepared or the way our mindset was after three wins, I don't know – it's a tricky one.
"I thought we did everything right after the Leeds game. Birmingham played last midweek, so I don't think tiredness was a factor. We spoke about it after the game but we can't really put our finger on what went wrong.
"We've got to remember that we are Millwall and hard work is what we base ourselves on. We have to go back to basics and put the graft in against Bournemouth, which is a big game for us."
Waghorn has been a regular starter since moving to The Den on loan and he has been pleased overall with his performances – Tuesday night aside.
"It wasn't the greatest game for me personally," he said. "I feel that the first goal was my mistake – I let the runner go.
"I try to work as hard as I can but I was tiring a little in the final 10 minutes – maybe that's because I haven't played a lot of games recently. I'll take it on the chin and make sure I improve on Saturday.
"With the lads winning, you kind of forget about scoring and you can't really complain, but hopefully I can get on the scoresheet once or twice."
