Busquets played with Xavi and Iniesta. That midfield system was perfect for him. The moment Xavi left and Iniesta declined, we saw Busquets get exposed more often.
Rodri at his best single-handedly dominates the game with his presence and contributes to everything. When Busquets was at his best, it was Xavi who used to control the game.
Pep doesn't start Rodri in the CL final and City lose. Pep starts Rodri in the CL final, he wins the game for City. Rodri is fit, City go on an unbeaten run for 80 games. Rodri is injured, City immediately look shaky and start losing games. A total leader on the pitch and extremely clutch. Imagine having this kind of impact and influence for one of the richest teams on the planet coached by Pep. Considering the player as a whole? It doesn't get more complete and well rounded than Rodri in that position. These last few seasons, he's been imperious.
Del Bosque once said that if you watch the game, you don't notice Busquets..........But the thing is when you watch a game, you can't help but notice Rodri all the time.
