Moving to another team in a different league at this time is not a bad option for Joselu considering his own age, which is no longer young. And new players like Mbappe who will strengthen Real Madrid next season can still be used as future players for Real Madrid. Apart from that, Real Madrid management always has a unique way of releasing old players and also bringing in new players so that the team's strength will never decline significantly because the players released are always older than the players who are successfully brought in each new season.
Actually, Joselu looking the realistic with his position if keep stay with Real Madrid after signing two top striker Mbappe and Endrick he will loss opportunity get more minutes playing such as this season get appearance several time as substitutes players.
Joselu has great opportunity behind his age over 34 years old and leaving Madrid for accepting other team offer with guarantee more minutes playing and get bigger payment salary.
Seems not significant impact for Madrid after leaving by Joselu, still has two top striker Mbappe and Endrick with some time Carlo Ancelotti moving Rodrygo for false nine position if both central forward make rotation or under perform.
Based on current rumors, that Joselu is interested by the Qatar team and the team is Al-Gharafa, I personally don't know about the Qatar league and whether the Al-Gharafa team is the top team there or not. Because I think, it is quite strange if Joselu accepts an offer to play in the Qatar league, because it looks like Joselu can still play in Serie A which is usually still actively playing old players. But, it also seems that if Joselu leaves, then playing in the Saudi Pro League is also a good choice, because of course it will get a higher pay too and it is good to end his career by getting a lot of money in the Saudi Pro League.
Joselu to Al-Gharafa is official not a rumour actually i still hope Joselu will continue his career in Europa because in my opinion although Joselu is not young anymore but with his current performance i think he still deserved to playing in Europa and previously Joselu was linked to the several clubs and the latest is Manchester United but unfortunately that's only remain rumour because Manchester United was never been bid for him and i think nobody will thought Joselu will accept Al-Gharafa as his next club and a bit unique about his this transfer process because before sell to Al-Gharafa Real Madrid has permanent Joselu with 1.5 million as transfer fee and they sell him to Al-Gharafa with the same price
About Al-Gharafa they probably cannot be says as strong team in Qatar league because every season Al-Gharafa was not involved to race title but last season they can finish at 3rd place which makes them will playing at Asian Champion League for next season and i couldn't find any information regarding contract duration Joselu in this team but i am sure Al-Gharafa will paying Joselu with high salary as commonly done by teams from the Middle East that they always give special treatment to players from Europa
