10. Bernd Leno – €25m
The former Bayer Leverkusen man was one of the first recruits in the post-Arsene Wenger era at Arsenal. And after just six Premier League games, he displaced Petr Cech in goal.
Leno has since been Arsenal’s undisputed #1, keeping 17 clean sheets in 66 appearances in all competitions.
9. Francesco Toldo – €26.5m
Francesco Toldo enjoyed a fabulous 20-year pro career in football. After failing to make it at AC Milan, he left for Fiorentina and established himself as a top goalkeeper. Therefore, Inter Milan signed him for an incredible €26.5m in 2001.
Ultimately, it was money well spent.
Toldo kept 95 clean sheets in 233 appearances for the Nerazzurri and won 12 trophies. Among them was the famous treble of 2009/10, which included his fifth Serie A title and only Champions League crown.
