People underestimate just how shit Ferran is
They think he has a place among top strikers just because he plays for a big club. He is by far worst of all starting strikers for top clubs in big 5 leagues at the moment
His level is Betis/ Villarreal and such clubs. Speaking of those two clubs Mikautadze is better than him and he is approx. on Cucho's level
Thuram is surely an improvement over Ferran which itself doesn't mean much. Whoever we sign is 99℅ an improvement over Ferran. But we have to aim for the best we can get. Thuran is a good option and a player who's proven his abilities on the biggest stage. But I think concerns about playing in a lone striker role are justified.
Ferran can't be anything other than squad player.
we have enough sample after 4 years of him here
Same hold for many others, like Fermin Casado Martin Eric Kounde (possibly also) Balde, who we have been forced to see as starters due to lack of options
The only ones currently that can legitimately be seen as starting material for a top5 (let's say) team in Europe are only Joan Garcia, Cubarsi (his 2023-25 version), Pedri, Raphina, and Lamine
For all the others upgrades are either desirable or simply a necessity
