Update, 7 June…Ben White (CB/RB/DMF) (Brighton) has been selected to replace Trent Alexander-Arnold. {Ben White called into England’s Euro 2020 squad in place of Alexander-Arnold, by Jacob Steinberg on 7 June 2021, at theguardian.com/football).}

Here is a link for England’s Group, with fixtures UEFA Euro 2020 Group D (from en.wikipedia.org).
England’s matches: v Croatia (13 June); v Scotland (18 June); v Czech Republic (22 June).

I have also made a full-squad chart for Belgium {from May 2021, here}. And previously, I made a 15-man squad chart for Scotland, after they secured Euro qualification {from Dec 2020, here}. I will post a full-squad chart for France on the 14th of June (which is one day before France’s first match in the tournament, v Germany).
