SC Freiburg goalkeeper Mark Flekken is interesting Brentford.
Kicker says Brentford are interested in the 29-year-old Dutchman in the event they lose David Raya this summer.
Flekken has a buyout clause of 13m.
Raya is only tied to the Bees until 2024 and he has already turned down several offers to extend his contract. A departure in the summer is therefore likely, with Brentford reluctant to lose him for nothing next year.
Flekken's deal also runs to 2024 and sports director Klemens Hartenbach said: "It's not supposed to go until May. We would like clarity from Mark beforehand and thus planning security."
