Joselu was rumored to be staying with Real Madrid for one more season a few days back then there were rumors that he was going to leave Real Madrid to join the Saudi League but now there are new rumors that he will be joining the Qatar League. The news of the transfer market is not very reliable, so when a player will go to a club and extend his contract with a club, these things seem to be rumours. If Joselu is thinking of leaving Real Madrid to join another club, I think the Saudi Pro League should be on his list. If any offer comes to him from Saudi League then I think he will accept that offer from Saudi League.
I also heard some rumors about Joselu. The first rumor was Real Madrid wanted to sign him permanently. It makes sense if Real Madrid signed him because Real Madrid only needs to spend a small amount of money. Joselu also has contributed well for Real Madrid in the last season. But since Real Madrid already signed Mbappe, Joselu may be not really needed anymore. I guess Joselu didn't want to stay in Real Madrid as a substitute player. He wants to play as a main striker, and he is also interested in the big salary from Saudi or Qatar league. So, it is normal if he wants to move to Qatar or Saudi league.
I've heard the same rumors you've heard about Joselu. Real Madrid want to renew his contract for at least one more season even though the player has no chance of playing in the regular XI. Real Madrid only want to keep this player in the team as an additional support. For example, if an important player in the regular eleven is injured, then he may plan to play in his place.
Since joining Real Madrid, we have seen the player warming the bench for more time. He should have thought about his career long ago. If instead of sitting on the bench of a big club, he came to the field from the regular eleven of a small club, then his game might have changed a lot and he could later play in the regular eleven of a big club. Since the prime of his career is gone, if Real Madrid offer him a year now, they should go from there.
