Barcelona begin the on-the-ground part of their England preseason against Birmingham City, and for once the friendly has a genuine headline attached to it. Karim Adeyemi, the German winger and the club's second signing of the 2026-27 project, is set to make his first appearance in the shirt at St Andrew's, according to Spanish reporting.

Kickoff is listed at 20:45 local time in England, which puts it in the afternoon for US viewers, roughly mid-afternoon on the East Coast and lunchtime on the West Coast. Birmingham are a Championship club and a genuine name in English football history, which makes them a useful test: organised, physical, and unlikely to roll over for a touring giant.

Two elevens, one plan

The detail worth sitting with is how Hansi Flick approached the match. He prepared two separate starting elevens for the game, rotating groups rather than running one team and making changes off the bench. That is a deliberate preseason tool, not a lack of decisiveness, and it is exactly the kind of thing a US coach can copy without a Champions League budget.

When you split a friendly into two distinct teams, you get clean data. Instead of a jumbled second half where tired starters share the field with fresh subs, you see one unit for a full period, then a second unit for a full period. You can evaluate combinations, not just individuals. You can give real minutes to players fighting for a spot without diluting the look at your first-choice group.

What Adeyemi brings, and why the first minutes matter

Adeyemi is raw speed added to Flick's wide rotation, a straight-line threat who stretches defences and attacks the space behind the last line. First minutes in preseason are not about the scoreline. They are about a new player learning where teammates want the ball, how the press is triggered, and what the coach demands without it costing points in the standings.

That framing is the useful one for your own group. When you introduce a new player, or a returning one, in a preseason game, resist the urge to grade the performance. Watch the connections instead. Is he reading the same triggers as the players around him. Is he in the right place when the ball turns over. Those are the things that decide whether a talented individual becomes a functioning part of the team.

The takeaway for your fall schedule

Preseason games are for questions, not for winning. Flick is using this one to get eyes on a new signing and to evaluate two full units under match conditions. You can build your own fall friendlies the same way: pick the questions you need answered, then design the match to answer them.

If you run a preseason friendly this fall, try the two-team split at least once. Play your projected first group for a full half, your second group for the other, and take notes on units rather than names. You will learn more about your depth in ninety minutes than a month of scrimmages will tell you.
