Well considering Serie A is done, surely we can play this way in each of our remaining CL games considering we're at no risk of burning out with our B team probably still being a top 2 side in this league
Kean, Caceres, Rugani, whoever we deem depth in midfield and Costa etc can play all the games. CR should play most games to keep him fit and firing. He's always thrived on playing as much as possible so despite the risk it's probably best he plays more often than not.
