I'd tend to agree. I''d leave Fernandinho out, then judgement calls would have to be made on Silva, Kompany and Aguero (i.e. whether its considered better to rest them or to give them minutes to try and get them fully up to speed). I'd go full strength as far as possible beyond that - assuming no-one else is struggling, of course.
If we then have to bring a couple of the kids in mid-week, so be it. Be better for them - and a clearer signal of our faith in youth - to play a couple alongside the first team against Kiev, than to send five or six out like lambs to the slaughter against Chelsea.
