They don't score many goals.
I think we'll be thin, given they're largely playing in centre mid and get no rest during international breaks. Perhaps Roberts could've hung around to cover. Perhaps he would've done if we'd have known this would fall through.
B Silva was fantastic against us for a Monaco and looks promising in our side, but I think he'll need a month or two to get up to speed, just like D SIlva did.
The way we play we'll leak goals. Sanchez probably gave us an extra 10-15 goals over Sane or Sterling. Those goals will add up over a season, like against Everton where we couldn't convert despite playing well in the second half.
