Mark Flekken: club-trained status

Whether Mark Flekken is club-trained at Bayer 04 Leverkusen is not verifiable on our record: it does not settle where he was registered between the ages of 15 and 21.

We count a player as club-trained when his record shows him registered with the club for three entire seasons or 36 months between the ages of 15 and 21 (UEFA's home-grown test), wherever he started and whatever he cost; time on loan counts for the club that borrowed him.
