We would piss the league if we dropped from cups like them. Van Diyk played 3000 minutes in the league, Salah and Roobertson 2900, Mane 2700, Firmino 2500. In our side Laporte has most minutes with 2600 and only Bernando Silva reached 2400 from others.
But with cups, our most used players come close to them. Plus none of their top players, except van Diyk played barely anything in national teams.
They've put everything into the league and are very lucky none of their top players picked any significant injury throughout the season. Yes, they are deep into CL, but they lost lot of games there and were lucky to go through group stage. They haven't rotated half of their first 11 at all for whole league season.
