I'll be honest, I was only saying I wasn't sure if I'd take him because I forgot the squad size was expanded to 26.
Rightly or wrongly I think Southgate will start with Foden on the left to allow Bellingham the number 10 role, which I personally think makes sense. But in a 23 you'd only likely have one other option for most positions. Rashford would have a bit of a chance because you can also use him as a striker, but mainly you've got Grealish who I would expect to get a place, at which point although I like what Gordon offers, it could be hard to take him.
With 26 there's more room to take him and, because he offers something totally different to Grealish and Foden, I definitely think he warrants a place. Mind I've always been able to separate club from country, no issue with mag players at all if they make the national team stronger. At least until the tournament finishes, then they can fuck off again!
I think Grealish will be dropped from the squad completely. The attackers in my opinion will be Kane, Watkins, Toney, Saka, Palmer, Foden, Gordon and Bowen.
