And Matthaus is still the best midfielder in the draft (along with maybe Davids) despite not being quite at his peak.
It still irks me a bit reading through Matthaus level in the early 90's and especially in that 90/91 season as him not being on the top of his game, which IMO is far from what in reality was.
Whilst he was excellent in 89/90 and instrumental for Inter's title win, his true sustained peak came exactly after the turn of the decade. The 90WC, then the 90/91 season where he topped whatever club level he was at ever before or ever since. He was a driving force and by far the best Inter player in probably 90% of the games played both in Serie A and during the UEFA cup run the same year. He won the FIFA Player of the year award in 91 for his feats at club level and not due to the WC win but to his exploits during that season.
In other words if we are to speak about his physical peak and ability wise is it really in 89 or 90 and 91? It's of course debatable, and you can perhaps about the number of games played - 2 seasons, although those numbers are pretty much close to whatever other numbers many players picked in 3 seasons or even more due to injuries during the time span, but ability wise I'm really surprised to be questioned during that particular time frame.
If you compare him with Brehme - both of him departed the year later, Brehme's career was pretty much done after that, Matthaus on the other hand, amassed something like what? 50 caps for Germany and retired with 4 more BL titles(3 in the 80's), 2 DBF Pokals, another UEFA cup title and so on.
So whilst I can see the point in the spirit of the draft and playing more games in that time span, when it comes to ability and during that time span, it's really safe to say that Matthaus was exactly at the heights of his powers and individually looking at him, no club performance beats that 90/91 season where he missed only 3 games, not even close..
