For example, you have Juve with 30 plus League Titles, but only 3 European Cups/CLs, whereas Milan has 18 League Titles but 7 European Cups/CLs. Forget 'right now'. Who is the bigger club overall? I don't think it's as straight forward as you say in terms of dismissing Milan, even though they have been failures recently.
Overall Milan are, but since we're talking about players moving and going, their current status in most players eyes is more important than overall stature.
Yes, that's more than what Milan did, but frankly, before we won the CL last season, we had won 1 League Cup in 8 years, so would you have had us as a smaller club than United and Juve at that time? I wouldn't have, overall, even if we had blips at that time. Were Leicester a bigger club than Liverpool before we won CL last season, because they won the League/a major trophy more recently than us?
I wouldn't have us lower than the Mancs, but most players would [not including Klopps time], given their dominance, given what they've achieved [despite our triumphs in Europe,etc.]
No Leicester of course aren't a bigger club, we've still had success in the last decade [when Leicester won it in 2015, the last ten years of that saw us win a European Cup, and get to another final, and challenge for the league multiple times in that period despite being a mess in between that].
I'm purely talking from a players perspective.
Top top players aren't going to Milan. There's nothing that would lure them that way. No world class players, no world class manager, nothing positive what so ever in recent years.
