This is as far as I have ever gone in terms of risking the ire of the footballing gods but... Given the amount of flight cancellations being announced I think I'm also going to look at cancellable flights and cross my fingers that we get past Forest.
In case anyone else finds it useful, here's a list of flights I compiled from BHX, EMA and LTN. Outbound Monday to Wednesday, return Thursday to Saturday. All prices are what Google Flights returned for one way and won't be what you'll pay for cancellable, return etc.

Outbound from LHR, LGW and STN. There aren't any from LCY.

Inbound.

Allow about 2 hours to transfer from SAW to Taksim which is closer to the stadium.
