I never doubt the quality of Kyle Walker, but I don't think Bayern Munich will sign him. If they transfer, it would be a good challenge for Walker, of course. I think he will go to Saudi Arabia to earn money because a 33-year-old football player will want to earn serious money in his last days.
If Bayern want maybe it's better for him to go to Bayern Munich. As long as you can still compete in Europe, it's better to keep playing there. Although maybe the salary received is not as big as in Saudi Arabia. Maybe at 35 years old he can go there. At least he will still be valuable and have the best stamina for the Saudi Arabian League. But Pep can keep it up, this is in preparation for a hectic schedule.
