I also did -8 and saved my FH. Using one would have been useful but I'll get more benefit later down the line.
I'd have brought in at least one of Martinelli / Saka but already have three Arsenal starters in Ramsdale, White and Laca and it's not worth shifting those, especially with other transfers to make.
Got rid of Salah early which I'll probably regret when he scores 406 goals against Leicester, but it's enabled me to bring in Ronaldo (although he'll obviously blank now, or the game will be called off) and Son.
I've also taken a punt and brought in Foden for Jota. I've got Bernardo too from before. I imagine only one of those two will start but even if the other comes off the bench, they could pick up points. I'll likely bring Jota back in soon but there's not point doing too much planning ahead atm.
