Giles stated that Flekken was a seamless replacement for David Raya, who set a high standard during his time with the Bees. Although they were expecting Flekken to remain with the team for many years, Bayer Leverkusen's interest in signing him made it possible for him to move closer to home and potentially play in the Champions League.

Giles acknowledged Flekken's significant contributions to the team and expressed his appreciation for his dedication.

Flekken's departure has left a void, but he will be remembered for his impressive performances both on and off the pitch.

Manu Sotelo, Brentford's goalkeeper coach, also praised Flekken's skills and work ethic. Sotelo noted that Flekken was a valuable asset to the team, helping to improve their attacking play and providing crucial support to the younger goalkeepers.

Sotelo highlighted Flekken's ability to adapt to the Premier League and become one of its top goalkeepers. He also commended Flekken's leadership and dedication to training, which had a significant impact on the team.
