I think we need to freshen things up a little after last night, get heads straight again and bring in some more experience when it comes to playing under this pressure.
I'd bring Stones in (if fit) to replace Guehi, not as punishment for last night's mistake but to give him a breather. Let Jonny talk Khus through the game. Guehi back in for Palace as Stones won't be able to play both.
I'd also play Phil on the right side in place of Semenyo. Semenyo has been very good in the main but again I think he'd benefit from a breather as he was rather ineffective last night, granted against a packed defence. Let Phil play on the right drifting inside to help centrally, with Nunes providing the width when we attack. I know Phil's form hasn't been great either but after a new contract, give him the show of faith of a start and let's see if he can play himself into a bit of form at home. He's also got a good record against Brentford.
Hopefully Rodri is fit to play but even if he is, will he be able to play Brentford/Palace/Chelsea in the space of 8 days? I'd go with Rodri for Brentford/Chelsea and rotate Nico back in for Palace.
