Arsenal 04 might have been the best at not losing games (apart from the time that season they lost to Chelsea in their most important game, got tonked by Inter, lost to Dynamo Kiev, lost to Man Utd and lost TWICE to Middlesborough), but they weren't particularly outstanding at winning. They failed to win a third of their league games.
And as if they would have been unbeaten if they had to face teams as good as Jurgen's Reds like City did last year
Thing is with them is that the league was truly appalling back then. Many of the best English players were plying their trade abroad at the time and there were barely any foreign players in the league, let alone good ones (the 3 at Man Utd were about the only good ones around that year). That Man U team were the best of a bad bunch in the PL. They showed their true level in Europe - getting beaten by Galatasary and humiliated by Barca in that period.
On Arsenal, the two defeats to boro were without a single first team player, league cup was for the reserves and kids , we topped the group with Dynamo and inter by destroying inter 5-1 at the san siro, knocking inter out in the process. The united defeat was with henry rested, and the chelsea game was an illustration of how tough it is to go 49 unbeaten because we beat them home and away in the league, and knocked them out of the cup, completely battered them that day in CL but didnt finish them off and they got their goal, city got knocked out of CL by you 7-1 on aggregate I think. Even then, the question was which was the
best premier league team, we were unbeatable in the premier league, other competitions are not included.
On Man utd in 93-94, that was an excellent team they had, they did badly in europe because of the 3 foreigner rule, I remember when they had to drop Schmeichel to play Roy Keane in barca in 94, they replaced him with a keeper called Walsh, he had a nightmare as barca smashed them. Sure they would not have beaten the Milan of that era, but Milan of that era would have dominated any time.
