Would our club spend upwards of 60m on a CB? I really don't think so.
On top Tot probably wouldn't even let go for that amount.
The last defender Barca bought, deemed expensive, was Koundé for 50m€. The point was that if the club finds funds to make one big money signing, I think the fans would prefer a top-class CB (for say 60-80m) over top-class striker for 150m.
VdV was one example but he's injury-prone as pointed out by
@Don Juan Laporta Estruch. But I can't think of anyone else who's left footed, tall, fast, good on the ball, still relatively young and yet with enough experience to adapt to the rigors and pressure of playing for a big club. Havent watched Murillo so I dont have an opinion. But he's 180 cms so thats an immediate no for me. lol
Buying unknowns/ low profile young CBs from lower leagues, unless they are supremely talented, never work. Given the unforgivable nature of being a CB, esp for Barca, any mistake will get you easily exposed and shatter your confidence. And since we are looking at a partner for Cubarsi, its best to choose wisely (experience + proven).
