Silva is going to be 29 this September. I can sort of see spending ~35mil for him now cause he probably is the best CB around, but it'd be silly of any team to spend more than 20m next summer. absolutely no resale value, even if defenders tend to have longer careers than strikers, increased injury risk erc. He's only worth this kind of money to teams like PSG, Monaco, City etc. Unless we buy him now, i'd rather not see us chase him again next summer cause i'm sure the price will still be too high.
Of course, if he does well at the WC i'm sure he'll retain his market value, but he'll still be a bad investment at the price they'd demand.
I didn't want us to spend 35m for Marquinhos because he's way too young and inexperienced, but he'd make more sense as an investment.
I don't know who the ideal replacement for Puyol is, but we need to find him soon. I like Vertonghen and Hummels but they're a bit too similar to Pique, imo. Kompany hasn't been himself in the last year or so, but City wouldn't sell him anyway. Juve wouldn't sell Chiellini.
We probably need to find some 20something talent that doesn't cost more than 20mil and invest in him.
