There are a lot of big teams who are very interested in all these players. And Manchester United seems to be really interested in Joshua Zirkzee. They are also in talks if I am not wrong. So I also do not think they will be able to bring all three players at the same time. By the way, the players are also not going to join if they get offer offer from better clubs. Just suppose they get an offer from Real Madrid to join, or even they realize that Real Madrid is interested in them, they are going to think twice before joining any other club.
By the way, I found something interesting.

Here it says that they are actually probably going for Lukaku and Abraham. I do not know how good of an idea this is to actually rely on them Lukaku is not in good form right now. At least not as a striker. And Abraham has missed almost the whole season because of injuries if I recall correctly. so this is going to be a big risk for Milan. High-risk, high-reward move.
Recently I've not found any news about Madrid really building intrest in any player and it's possible they wouldn't because they have got a really solid squad already at the moment so they may actually not really need to sign new players who they may likely be keeping on the bench Al through the season, and Manchester united isn't a small team to say they will be waiting for offers from other big team, just that at the moment Manchester united may really look like they are not in their very best form to be an to get their careers looking good but financially Manchester united isn't in a poor state to be able to cater for theses players. Abraham is currently an injury prone player and I see that as a big problem the team may have to face in the long run if they happen to sign him, Injury prone players except they are fully recovered,are usually not a really good deal and they end up not getting the team to get complete value for their investment. With lukaku, it's possible he may get to improve but I don't see him as a good deal as he's aging already so his efficiency I'd going to drop and even his improvement may not be all that significant.By the way, I found something interesting.
