Set up like this.
Raya
Timber Keane* Virgil Andersen
Foden Cunha Rice Semenyo
Haaland Ekitike
Dubravka // VDB Guiu Ba
Your Richards > Keane move is a decent one.
Your bench leaves an awkward situation if Timber wasn't fit.
I'd consider one of the defenders > Hall & start him, at least that gives you some cover too.
Semenyo can probably be moved in soon. Not sure who I'd go. Probably fine to keep this week, if you're making another move elsewhere - so you're banking that extra FT for later.
