Haha.. You want to compare achievements? What would you define ' old liverpool ', how about ' old arsenal '? Have the new arsenal won anything this past season? Don't talk when your team can't even play properly on the field, same kind of analogy.
I would like to remind you that Liverpool is currently the top team in Europe, winning the champions league, going to the finals, going to the semi finals. Winning the FA cup.
Don't doubt Rafa's credentials. They cannot be compared because of the time gap. You tell me not to talk about old liverpool, yet you're going on about Ferguson and Wenger's past achievements, seems pretty contradictory. How can you compare when Rafa was in liverpool for like what, a few years? Has Ferguson or Wenger brought a team to champions league success in their 1st/2nd term in charge? No, from what I saw it was a team of mediocrity.
PS: You wish Arsenal could be in a position to slip up this season, oh yes, I went there.
