With the departure of Benzema the biggest question has become "Who will take his place in his position?". Rodrygo is normally a right winger and he can play on the left wing or as a centre-forward when there is a need as well. However his statistics hasn't been very impressive in times he played as the centre-forward. He is much more beneficial as a winger which can be understood from his statistics there as well - 10 goals, 9 assists in 25 matches. He should stay as right winger in the lineup as much as possible.
From now on I hope to see a solid attacking trio on the front. Vinicius on the left, Rodrygo on the right and a solid centre-forward in the middle. I wonder who that striker will be. Martinez and Kane have different characteristics. Kane is more like a complete forward who can do a lot of things to help the team. He has made many assists to Son so far in addition to his amazing finishing skills.
But Martinez is also a great scorer and much younger. If they have to pay 100+ million euros for each one of them then it is up to what kind of a striker they are looking for exactly.
Real Madrid boss said once that he will try to attract Kane this season and Mbappe the next one. That was said few days ago. Meanwhile Real Madrid seems interested again in Mbappe although the player said in the past that he will continue to play with PSG to honor his contract.
Getting Kane then Mbappe seems unfeasible since Kane will know that he risk to play less in the future in Real Madrid. Better to try to bring Mbappe this year in my opinion.
