Suarez is the best number 9 of the last decade for me, no contest. And I'm still bitter we didn't get that cheat. We absolutely needed someone of that endeavor.
I actually agree the Barcelona players are past their peak, some of them, and isn't as good as their treble winning sides for example or even their last UCL win team. But Busquets, Alba are still the best in their position. Ter Stegen, Pique are very close to the best, with the rest of them easily top 10 players in their position. They are still way above us, make no mistake about it. They are 3 or 4 leagues above us. Their bench players will start for us
