The greatest club sides I've seen are AC Milan (Rijkaard, Gullit, Van Basten), 87-88 Liverpool (Barnes, Beardsley, Aldridge), Ajax (Kluivert, Litmanen, Davids, Seedorf) and now this Barcelona team. All four gave me the feeling that when they stepped on the pitch, they weren't going to lose. And if they did, it was a massive shock.
