Kicker reports that Chelsea goalkeeper Petrovic is a candidate for Leverkusen, with Matej Kovar will more than likely leave the club, while Lukas Hradecky will be demoted. Espanyol goalkeeper Joan Garcia has been linked with a move to Die Werkself in recent weeks and is still a summer target alongside Stefan Ortega and Noah Atubolu. However, Leverkusen are trying to find keepers for less than €30 million (£26m/$34m), and Petrovic could be the perfect option.
