Millwall got a huge kick up the backside on Tuesday night when they were thrashed 5-1 at Peterborough.

The performance was embarrassing for our supporters from start to finish. To lose so convincingly is a worry and was unexpected despite having given up a two-goal lead in the previous match to draw 2-2 away to MK Dons.

We might be missing midfielder Shaun Williams but we believed the team were on a much better level after the great end to last season.

This result has shown that we cannot just turn up and expect to win matches if we don’t do the basics right. We need to defend much better as a unit and then pass the ball better through the midfield, looking to retain possession for much longer than we have done.

The real worry is the defence. We lost centre-back Mark Beevers in the summer, breaking up the good partnership with Byron Webster. Tony Craig stepped in and had solid matches against Oldham and Barnet. But with a couple of sub-standard performances since then, Craig needs to get back to his best otherwise Sid Nelson will have to return.

Work to do

The two away trips to MK Dons on Saturday and then Peterborough on Tuesday night (August 16) were always going to present a decent examination.

The results have shown there is plenty of work to do. We need to bounce back quickly as Saturday sees us back at The Den for another stern test against Sheffield United.

We took a good following of more than 2,000 supporters up to Milton Keynes and were in good voice especially when we took a two-goal lead thanks to an own-goal from ex-Lion Ed Upson who diverted a header from skipper Tony Craig past his own goalkeeper. Then David Worall scored his first for the club.

At that point, following on from two comfortable wins, with clean sheets in our last two matches we thought we were cruising to another victory but MK Dons pegged us back and were level just six minutes later.

To give up a two goal lead was disappointing but nothing compared to the crushing misery of a thrashing by the Posh.

What the manager said

Referring to the Peterborough match, manager Neil Harris told the club's website : "I thought we were poor from start to finish. Some of our decision making was ridiculous. However much luck we have or don't have, you have to be calm and make good decisions.

"For periods of the game we went into our shell and panicked. That is not my team. We can have one of two having an off game, but tonight we had pretty much everyone.

"I'm hurting and the players in the dressing room are hurting, some more than others. We gave the ball away cheaply. The players will be embarrassed. We have the perfect opportunity to put that right on Saturday.:
