Posh boss Darren Ferguson refused to press the panic button after his team suffered a successive League One defeat.

The east Londoners are the surprise package of the season, but proved their excellent form, which has taken them to the top of the table, is no fluke.

Tommy Rowe had given Posh the lead, but two goals from former Norwich City loan player David Mooney and one from Dean Cox meant Posh are now five points behind their visitors, in third, and three behind Wolves.

'Great credit to them, they're really going well at the moment,' said Ferguson, who saw his side lose at Colchester the previous weekend.

'A team that has won that amount of games in 15 is not a fluke and we knew we're playing against a good team.

'You get days like today, but no league is ever won in November so there's no panic.

'I've watched the goals back and they're awful goals to concede, you can't concede goals like that and that was disappointing.

'I would say that we haven't been playing up to the standard for four or five games now, but we've been winning, not that that's ever papered over the cracks for me.

'I always analyse the performance as well as the results.'

Not surprisingly, Leyton Orient manager Russell Slade was more upbeat.

'It was obviously a very big test, a very big hurdle and obstacle for us to overcome,' he said. 'I thought we did that extremely well.

'David Mooney's form has been remarkable and his performance today was excellent, but it would be very difficult and unfair for me to pick out one player today.

'I thought as a team we looked very solid, very resilient and a threat going forward.'

Posh went ahead on 26 minutes when a low free-kick from McCann caused panic in the Orient defence, it appeared to strike Rowe and Tyrone Barnett before rolling over the line. It was level on 38 minutes when Mooney spun and fired home and four minutes into the second half the visitors went ahead after hesitation at the back involving keeper Bobby Olejnik and Michael Bostwick allowed Cox to nip and lob the ball into the unguarded net. Mooney wrapped it up on 58 minutes when he drilled home an angled drive into the bottom corner.
