Zidane should give him some more opportunities. I think Bale should be as hard working as cr7. Only through hard work can he change his position.
I think there are 2 things that made Bale let go of Real Madrid in the previous transfer market,
1. His performance currently down (as we already know)
2. His salary problem at Madrid (we know after Covid the team must start thinking about the best way for efficiency)
For these two reasons, I think it is enough for Real Madrid to make a decision to accept loan offer from Spurs. Regarding the return, we have to wait for the end of the season, but the chances i think still 50:50 atm.
