Difference with Silva is we knew this was the case with him from day dot, asking him to play three games in a week at 36 after two games on the other side of the world is a huge ask so we have to prioritize. There's not one outfield player in the modern era playing three games a week at that age, certainly not at our level.
We will have to make decisions like this with him throughout the season. I do agree we need atleast one constant though, hopefully Zouma with AC/Tomori filling in whenever we need to rest Thiago.
Mourinho's not really someone to use as an example on this score.You're right he doesn't rotate as much but he often aggravates issues by making players play when they're not 100%, Terry in his first spell here was rushed back and then put out for ages, second spell he refused to rest his core players and made Hazard play through injury and that ended up with us fighting the drop and our star man not scoring till April.
