The agreement between Brentford and Liverpool includes a reported fee of £12.5 million, which may increase to £18 million based on performance-related bonuses. This deal will be finalized once Mark Flekken completes his transfer to Bayer Leverkusen.
Flekken's move to Leverkusen is nearly confirmed, as the two clubs have already agreed on an £11 million fee, and the player has also reached a personal agreement with Leverkusen.
