I don't think if Joselu was the alternative player for Benzema because the most important thing about Joselu is his age and he is not younger than Benzema to take his place in Real Madrid for years and On the other hand Joselu was never on the same level with a player like Karim Benzema.
Real Madrid needs a player like Mbappe or other young center forwards to make them sure in the next seasons.
To be honest Joselu is very old and doesn’t have any good news to bring for Real Madrid, the last three matches i really got impressed with the middle field Bellingham in his 20 age only he managed to be the striker of LaLiga in the beginning of this season beside saving Real Madrid in their last match against Celta Vigo. The same thing with Barcelona they both need a real strong striker this season in order to do something in UCL, otherwise we going to see the English teams taking over and winning every single trophy.
Manchester City still the most strong team i can suggest taking the UCL again this season if everything stay the same way as this. But honestly this season has much less attention and competition after the big players moving out to Saudi Professional League and leaving UCL less attractive as many people loves to follow player and not clubs.
Signing joselu was a bad decision but since he was coming with very cheap fees and it's not a serious problem for real madrid. Joselu's salary was also very low. Bellingham had a multiple role in madrid. Bellingham to playing as an attacking midfielder, while he took on the role of central striker, resulting in more goals for the club. I can't imagine if real madrid was not recruiting him for dortmund. it will be a disaster for madrid as the club still find about how difficult in getting a new striker that can play as good as benzema when he was still there last season.
Joselu is far from our expectation and i think that this guy will always be benched as ancelotti doesn't really need him at this moment. The club is now having bellingham who played in multiple roles at the same time.
Madrid needs to find a good striker to strengthen its attacking line. Ancelotti needs to bench Joselu and make a move before the end of transfer season to find a good striker for Madrid's attacking line..
Many madridista has been pushing him in signing the new striker but there's no signal from madrid regarding this.
