Most PL clubs don't get European football, but that doesn't mean we should settle. I get that it's a risk but as you said, some clubs can do better than others. It's not just a matter of rolling the dice as there is some methodology in scouting the right players. We can't afford to buy expensive (80m+) players.
I'm happy with the deal to do Porro. There is definitely a premium we are paying but he's a good player, and theoretically if he keeps improving and does well here, he'd be worth at least 60-80m. That seems to be about our limit.
Atm we are still rebuilding, with several first team signings still required in the summer - i do think we're nearing the end of it though and so moving on from next season we should be in a position to start dropping big money on individuals. Maybe even this summer if there are some cheap/free players to cover a couple of positions we need. Pickford & Ndicka potentially covering GK & CB for 25m - could leave a chunk for the other CB position and then a loan for RWF or vice versa
