He would want really high wages too, it’s a good idea to steer clear imo.
Gareth Bale will be happy to sit on the bench all season whilst collecting his monstrous paycheck, but obviously Real don't want that. Most clubs won't want to pay a lot for him because of the problems you said, but also because they won't want to pay the wages and there's very few clubs that can even afford to do so. Real should look to loan him out and get what they can for him if they're not going to play him as they're just pissing money away in the process. I'm sure some club would be willing to pay a portion of his wages and it's better than nothing. If he plays well and remains injury free then they could make an offer for him but I really can't see any club coughing up the amount Bale will want in wages and I doubt he'll leave Real for less than he's getting now as financially it doesn't make sense, though I'm sure he would like to get some game time but at what cost? I think he would be a good fit for United. If that rumoured deal was true about swapping Pogba for Bale and a few other players I think they should take that but doubt it'll happen. If Zidane has no intention of playing Bale (even though I think that's silly) then they need to offload him ASAP.
I had a dream Bale went to Newcastle to play under Mou (who became its manager after the City oiler's cousin bought the club) and lead the club to a top 6 finish.
Bale cooperated with Mourinho and the results didn't bring something successful.
Mourinho didn't gave him enough opportunities and it seemed that he didn't believe in his abilities. Of course, In a team without so many stars like Newcastle facts will be different, but still I am not interested in seeing this scenario.
