West Ham is playing Fulham that weekend, which is a derby so that atmosphere will be crazy. Huge stadium, should be able to get tickets, although since it's a derby they'll be a little pricier than otherwise.
Chelsea is playing Wolves. Not an important game so tickets should be easy to come by, although they have UCL games midweek before and after that match, so good chance Pulisic will play. If you want to watch Captain America, this is your best chance IMO.
Arsenal play Liverpool. Gonna be some expensive tickets for this one, but should feature some great football.
Crystal Palace play Leeds. Two Americans, Brendan Aaronson and Tyler Adams play for Leeds and have a good chance to feature here. If Richards makes the move to Palace, you could see 3 Americans in the same EPL game. That'd be great.
Can't go wrong with any of these IMO. I think I'd choose the derby just for the crazy atmosphere, but I'd love to see Pulisic play in London too, so for me it'd come down to between those two.
Games aren't announced yet, but Group stage UCL games will be that Tuesday/Wednesday too and if Chelsea or Tottenham have a home game that week it'd be killer to see a UCL game IMO. Likely quite expensive though.
