Bale coming back is not even worth considering, in my opinion. In my mind I don’t even get as far as debating the pros and cons of having him in our team, as it’s incredibly unlikely to ever happen.
Bale will want to stay at Madrid. We all saw his determined attitude to prove how great he is.
If he’s not wanted at Madrid he’ll most likely want to go somewhere where his career is perceived as at most a step sideways. Now I’m not saying that this current team (form aside) isn’t one of the best teams in Europe, but that going back to the club that sold you is definitely perceived as a step backwards for the player and his agent. The Manchester clubs are the most likely destination, and the smart money is on United as they have been desperate for him to be their new Giggs for ages.
When you throw salary and injuries into the mix it’s just a list of reasons why it won’t happen. The stars would really have to align before we can even start asking if he’s worth it.
