#2 The "back to home" factor
There have been certain players who lost have their groove in foreign leagues. It should not come as a surprise if Gareth Bale's return to England turns the tables dramatically for him. It is indeed surprising to see a player of Bale's calibre struggling with injuries.
The Welshman could perhaps be facing the general conditioning problem where he is not accustomed to Spain. Maybe, a return to the Premier League enfolds an altogether new phase for him.
Bale would soon be 29, it would be his last big contract at the top level. Clearly, moving to Madrid was not his "Best" decision. There would be absolutely no harm in trying different things.
If the former Spurs man does plan any such return, what could be better than entering the Theater of Dreams.
