Joselu is indeed not young anymore and he doesn't have all the attributes of a world-class striker but I think he can still contribute to Real Madrid. Joselu didn't have many game hours last season because he was indeed the second line of players, but I think the 2 goals he scored in the semifinals against Bayern Munich will not be forgotten by Real Madrid fans because it was that contribution that brought Real Madrid to the Final and ultimately won the Champions League trophy. I think that, apart from feeling that Joselu can still make other contributions, this permanent transfer can also be considered a reward for Joselu.
As a player, actually joselu does not have quite a brilliant achievement and career as a striker, since he has had a career in various existing teams, so far joselu has spent more of his career as a reserve player and it is very difficult to gain trust as the main striker in a team, this is very natural because so far his performance has often been inconsistent, Playing in a big team like Madrid is of course quite proud but still his name will always be covered by the prestige of other players so far, this season Joselu has become an important part of Madrid because they do not have a central striker after losing Benzema, but in fact sometimes Ancelotti often plays a formation without a central striker.
Joselu has now been officially made permanent by Madrid, after previously being a loan player from espanyol, the loan terms that require a permanent purchase of course make Madrid inevitably have to make joselu current status permanent, I think if there are other options listed on the loan contract of joselu, of course Madrid will not make it permanent and prefer to return it to espanyol.
