Obviously Milan were the choice team, by far and away the best in the world at the time, but as stated earlier, their 3 foreigners were Gullit, Rijkaard and van Basten, there was no room for another huge name overseas player at that point, and I'm not going to venture that Gazza should've muscled one of them out. Likewise Inter had Matthaus, Brehme and Klinsmann - all 3 WC winners (teams liked to have their 3 foreigners from the same nation it seems!)
Comparing modern midfielders and the 'top clubs' wanting them to players like Gazza/Platt et al is unfair, because your Real/Barca of the last 15 years can fill a squad with foreign stars and not worry about the cost, back in 91 that was impossible due to foreigner rules and teams simply did not have the money coming in to do it. I mean, for comparison, Gazza cost £8.5m, only a year earlier Man Utd as an entire club was on the verge of being sold for £10m. Again, to point out that Gazza's transfer was more than Coles record move 5 years later, and it was only Shearer's move to Newcastle that set the bar higher.
