Anyway, Kyle Walker has already get many titles with Manchester City so indeed, it is quite reasonable that Kyle Walker might prefer to earn more money with playing in the Saudi Professional League. After all, even if for example Kyle Walker left and joined Bayern Munich as well, in fact Bayern Munich basically only has dominance in the Bundesliga but not the Champions League. Thus, choosing to play until his contract expires at least for one more season at Manchester City and then leave to playing in the Saudi Professional League, at least i think it will still be a reasonable choice and still feasible for Kyle Walker who is approaching retirement.
Walker was the best player with good techniques in the Manchester games.Many people want to join the Saudi Arabia League as you said,if the Walker decided to join the league.Walker get huge quote from the Saudi Arabia Club as like they offered the Mbappe.Some people think Kyle Will announce his retirement after the Manchester City,but my opinion he will get into the Saudi Arabia Leagues.Because most of the football players will get into Saudi Arabia League as his destination.Because the players can earn their settlement money from the Saudi League.They are ready to buy most of the European players at any cost for their deep origin.Kyle Walker is the best player and good analytical thinker.So expect him in Saudi Arabia League of 2023-24.
