Despite skipper Steven Gerrard’s lukewarm penalty being saved by Ben Foster, centre-back Agger refused to hide behind excuses for the 2-0 defeat on Monday.

The Danish centre-back was slated by fans on Twitter after being at fault for both West Brom goals — and was then applauded by them for AGREEING with their criticism.

Agger, 28, tweeted: “I agree with most of you. My performance in the last 10 minutes was NOT good enough. It’s as simple as that!!!!! But thank you for letting me know.”

Just four minutes after Gerro’s 77th-minute spot-kick, Agger left Gareth McAuley in acres of space to head home the Baggies’ first goal.

And then in the dying seconds Romelu Lukaku skipped clear of the tattooed defender to seal the win.

Agger’s admission of guilt was roundly applauded by supporters, in stark contrast to the reaction from Jonjo Shelvey.

The midfielder, 20, was also the target for stick on Twitter from Anfield fans — but had a pop back.

Shelvey tweeted: “Love people giving me stick when half of the people on here haven’t got a clue what they are on about #welldone #keyboardwarriors.”

Agger and Shelvey will board the Reds’ flight to Russia today as Liverpool resume their Europa League assault at Zenit St Petersburg tomorrow night.

The freezing temperatures in St Petersburg mean it is too cold to train so Brendan Rodgers’ team delayed their flight by a couple of hours so they could get in a session at Melwood.

Kop boss Rodgers plans to field his big guns for the first leg of their last-32 tie.

And he is convinced they will bury the misery of their Baggies blunder when they take on the Champions League drop-outs.

Rodgers insisted: “These players were very disappointed because we went into the West Brom game with the best home defensive record in the Premier League.

“But they will react in the right manner. They’re good guys here, they want to work well and are very good at moving on.

“That’s something we’ll have to do if we want to progress.

“The Europa League game is a good opportunity for us to progress in a cup competition.

“We’ve got to get the disappointment of Monday night out of our mind and refocus on this now.”
