Ancelotti did not give him a chance to start even after his goals in the semi-final against Bayern, so it can be said that Ancelotti is not changing his working strategy and there will always be a place for Joselu on the bench. Moreover, with the arrival of Mbappe, this situation will worsen, I doubt that Mbappe or Rodrigo will be on the bench. But apparently Joselu is happy with this, he goes on the field for twenty minutes, scores several goals, but he plays in Real Madrid, everyone makes their own choice.
Yeah, Joselu should've know he will rarely play, this season Real Madrid also benched him for many times, so if Joselu isn't happy with that, he can reject the offer.
But, I really doubt Joselu will reject the offer because he's become a professional football player since 2009,
but he only get trophies when he play for Spain and Real Madrid. This must be his biggest achievement after playing football for at least 15 years, he has no chance to win any trophy if he play for mediocre team.
