I've tinkered a million times and am finally settled.
I've accepted that none of the 4.0 defs will play so I'll just take a punt on Brrr and drop him to third on the bench and see if any one of these bums gets game time once the season starts. I'd rather do that and go with the team I like as the chance of using that 3rd sub is slim to none more of the times.
McCarthy
TAA, KWP, Dallas
Salah, Son, Auba, ASM
Werner, DCL, Mitrovic
Subs: Steer, Taylor, Reed, Buur
Swapping Son and Auba to KDB and Bruno first two transfers...
I think that's quite balanced and is the team I keep coming back to.
