The united team of those two season knew how to win just like this Liverpool side but we had a good depth in comparison tot his Liverpool side. And again I will sound repetitive but the league was much harder. Yes there were no City, but there were other formidable teams who would pose more threat than the current lot. The current Arsenal side or even the United side are just bug by name but their performance is of a genuinely midtable side. Spurs, well are no good either and are matching Spurs from then or maybe are even worse. The ARsenal, chelsea or even the Liverpool side from that era were very good and much better than the 3rd/4th/5th side from this season.Over the two seasons 07/08 and 08/09 when United won the league twice, we failed to win 10 or more games in both of them - we scored 68 and 80 goals respectively, not... insane. There were no City and Spurs competing back then, but in the top ten you had Villa, Blackburn and Portsmouth... as well as Derby, Sunderland, Boro, Hull and Wigan at the bottom. Liverpool will perhaps end up at 3 or 4 games that are not won this year and around 90 goals, depending on their motivation and what happens in the CL. Any given team will only play another (potentially great) team twice, there are 36 other games to play as well and plenty of banana skins. What they are doing this year is potentially unbeatable, as much as it hurts to admit
City pretty much did the same for 2 seasons and now Liverpool are doing the same, doesn't that more about the league in general.
