Once the age of a player get closer to 35, he should take cautions about his future.
It is difficult to get a regular place when the player is over 32 years old, even Luka Modric, who is Real Madrid's mainstay senior player, currently sits mostly on the bench. He realizes that at his current age it is quite difficult to play full time because Real Madrid is also We already have young players who of course have stronger stamina. So the senior players will one day be replaced and one by one the Real Madrid seniors will leave, like Toni Kroos, he decided to retire early even though he is still younger than Luka Modric. But what Juselu did was actually not the wrong decision. He has the right to determine the end of his career because it is very likely that he will retire soon so he decided to leave and choose a club with a bigger salary and I quite agree with Juselu's decision. With Mbappe at Real Madrid It seems like there is no place for him to be in the starting 11.
Basically, when every player gets older and experiences significant decline in performance, plus there are more young players who are great and have potential, those who are older will often sit on the bench.
Moreover, for Real Madrid, which already has quite lot of young players and can always be relied on when they are part of the main squad, this is also the reason why Ancelotti did not try to retain his senior players when he decided to leave and retire.
But by the way, it cannot be denied that those who are older and decide to leave in search of big salary, the last resort is Saudi football and there are already several players who have done this.
Everything is clear and Joselu also accepted the offer made by Al Gharafa and played in the Qatar League, but this will be the same because Saudi and Qatar are two countries that both develop football very well.
