Peterborough manager Darren Ferguson backed his dad's Manchester United side to claim their 11th Premier League title this season - after seeing them win 2-0 in tonight's friendly at London Road.
A scrappy own goal by Posh defender Russell Martin was followed after the break by a fine 25-yarder from substitute Daron Gibson.
Ferguson junior predicted: 'Whoever finishes above United will win the league.
'They will take a bit of beating. It will be the usual top four, but I can't see anyone getting above them.
'He hasn't added to his squad yet and I don't know if he will - but the squad last season was the best anyway.
'The size and quality in depth in the squad is the difference.'
Coca-Cola League One Peterborough were the better side for most of the opening 45 minutes - in which United fielded the likes of Carlos Tevez, Rio Ferdinand and Patrice Evra.
The Posh boss added: 'It was a very encouraging night for us, in the first half in particular.
'I thought we just edged it, and their goalkeeper made some very good saves.
'If Russell does that on Saturday I'll kill him. I'm glad that he got it out the way in a friendly
'It was a good experience for my players. They had eight internationals out there in the first half.
'The second half petered out a bit, and we gave the ball away a bit too easily. When you do that with players of the quality United have, it takes you a long time to get it back.'
Sir Alex Ferguson refused to comment on the future of absent star Cristiano Ronaldo - instead highlighting the performance of Brazilian twins Rafael and Fabio Da Silva.
He conceded: 'Peterborough were the better side in the first half and should have been 2-0 up.
'But there were some plus points for us as well. Rafael Da Silva played the full 90 minutes and was pleasing, and his brother Fabio played 45 minutes as well.
'I was really pleased with their contributions, and it will be interesting to see how they get on this season.
'The squad we had tonight will play Juventus on Wednesday - with Ryan Giggs, Paul Scholes and Gary Neville to come in.'
