Assuming we beat Napoli next week, there will be no excuses for Foden not to play a part in our final two CL games.
In my opinion he's almost guaranteed to play in the Carabao Cup 5th round and Shakhtar away (we should beat Feyenoord at home) but like you say, it would be great if we could beat Napoli away and then we all get to see him vs Feyenoord.
