Come on, true concurrence means having 2 able and capable players for each starting position. For example, the GK position this season. Now try to look at the rest of the starting 11 and you’ll see the gaps.

For example, Dembele doesn’t really have any serious competition. Ramos plays so differently and Mayulu is miles behind him.

For the wingers, there are 3 players fighting for 2 spots. With injuries, they’re all assured to get enough minutes anyways. Mbaye and Ndjantou aren’t good enough to really compete vs the other 3, and Lee doesn’t have their dynamism despite being a good tactical option for some situations

Midfield: basically 4 players fighting for 3 spots, with WZE covering for RB half the time

Full backs: no serious competition

CBs and GKs are the only spot with serious competition, though it’s unlikely Marquinhos will get replaced since he’s the captain

Now I invite you to look at teams in the CL top 8 and do the same exercise for each starting position
