I also watched Milan games often and there's no doubt Rossi was a very good keeper. Sacchi bought him due to his allround game and his ability to play out from the back which was alien in many countries at the time. His ability to play sweeper keeper was quite rare at the time and I remember one season he saved several pens to save Milan's blushes. The reason he didn't play for Italy was simple. He wasn't as good as Toldo or Pagliuca and Italy at the time had a embarassment of riches in that department. The Milan team was good defensively but at the time the whole collective was geared upto to defend due to a point being awarded for a draw and 2 points for a win. But to say he wasn't a good keeper due to the collective and personnel isn't true imo. Milan under Capello won the title by only scoring 36 goals and conceding 15 one season and were outscored by 10 of the 18 teams in the division. One could make the argument that some of those legends in defence would also also struggle in a more expansive setup. Sacchi bought Rossi due to the player fitting into the revolutionary style he had implemented and wanted a keeper with a particular profile. If you asked Guardiola or Van Gaal on who they'd pick out of De Gea or Ederson and I have no doubt they'd both choose the Brazilian due to his superior ability on the ball which is a big part of both coaches coaching mantra. So in the same way, it was Sacchi's footballing mantra that took precedence when choosing Rossi as his keeper.Seba Rossi was a very average keeper, I assure you as I watch most of Milan's game at the time. There's a reason why he never represented Italy despite being part of what I think to be the best XI I've ever seen. He wasn't very good. Yet Milan had no issues with that mainly because Baresi, Tassotti, Costacurta, Maldini and Ancelotti/Rijkaard would cover his arse. Barthez (France) is yet another example of a meah goalkeeper playing at the back of a magnificent backline.
I agree with you that a decent goalkeeper is always needed as reaching the perfection reached by AC Milan of the time is almost impossible. However what we at United ask from a goalkeeper is way beyond to that especially in the past few years. We're used to DDG constantly bailing the defence out. Once that stopped the criticism came on him like an avalanche with legends like Keane now saying that he always thought that DDG was overrated. That's disrespectful.
We won't get rid of DDG and unlike Sanchez I am not that worried about that. There's still a decent GK in DDG and he's probably still the best goalkeeper we have. However its clear that he can't do it on his own anymore. We've got a defence which costed a measly 180m-200m. Just ask yourself which of these guys would make it at first team level either in the treble side (Gaz, Johnsen, Stam, Irwin) or the 3rd CL side (Gaz, Rio, Vidic, Evra). I would struggle to come out with even 1 name. That's certainly not good enough.
I can't be bothered scrutinising this or that player. The defence should be seen as a unit rather then as individuals. Bruce and Pally were nowhere near to WC but they made it work. Same with Juventus whom back to Lippi times, used to have a very solid backline despite relying on average defenders (Montero, Torricelli, Iuliano and Pessotto). Unfortunately I can't see that happening in our present side. DDG needs to be more physical and far more vocal. Lindelof and Maguire are just too slow and honestly I have yet to understand what Lindelof brings to the table apart from the fact that he's better then Rojo and Jones. Meanwhile having 2 defensive full backs is overkill especially since Shaw isn't that great in defending either. Ah and I almost forgot, someone need to tell Fred & McT that unless they transition quickly to top quality DMs then there days as first team players will be numbered. United need players that can stand up and be counted + players that can compliment one another. Shaw-Maguire-Lindelof-AWB with McT/Fred as DM simply don't cut it. I hope we'll sort that before Henderson return. The last thing we need is for the hype to go overdrive only for the guy's confidence to be shot once its evident that he's not going to bail the idiots in front of him as good old prime DDG used to do. We've already ruined Foster's and Howard's career. Let's spare Henderson from that misery.
I've never rated De Gea as being world class which is a minority view on here but a popular one in the keepers homeland. To only be good at shot stopping isn't good enough and his allround game just isn't good enough. Worldclass players prove themselves for club and country at the highest level and De Gea has never done that and he plays for a very good international team. Contrast that with the allround brilliant Schmeichel who elevated lowly Denmark and was a key cog for them winning the Euros. That's what you call world class and I agree with Keane because the standards of world class shouldn't begin and end at domestic level. De Gea has been a very good shot stopper in the English league but out of that he's been found wanting.
Barthez was good for France. He might not have been world class but was good in goal for them when they won the WC.
Lippi did have a well drilled unit defensively but also had Angelo Peruzzi in goal who was a very good allround keeper even if he was a little on the short side but was genuinely world class and proved it in the champions league too.
I don't know if Henderson is gonna be good enough for us long-term but feel he has put himself into contention for a chance as our #1. And I also disagree that the confidence of the likes of Howard and Foster was shot when given the chance. They just weren't good enough for the standard required and had never played at EPL level before unlike Henderson.
