Paris Saint-Germain interested in Frankfurt goalkeeper Kevin Trapp

Paris Saint-Germain have made an approach for Eintracht Frankfurt goalkeeper Kevin Trapp, according to the German club's CEO Heribert Bruchhagen.

Trapp, 24, signed a new contract at Frankfurt last season, tying him to the side until 2019, but is reported to have a €9 million release clause in his contract.

Bild reports Trapp flew to Paris on June 4 to hold contract negotiations with the Ligue 1 champions.

Bruchhagen told Sport1 "We know that there has been an offer and Paris approached Kevin."

Trapp joined Frankfurt from Kaiserslautern in 2012 for a reported fee of €1.5 million and has played 75 Bundesliga matches for Eintracht since then.

He played seven times for the Germany under-21s until 2008, but has failed to break into Joachim Low's senior side since then.

New Eintracht manager Armin Veh said: "In football you have to be open for discussions. There are only a few clubs like Bayern [Munich] that can afford to refuse to negotiate."

Veh added to Frankfurter Rundschau: "It has to be our aim to buy a player for cheap and sell him expensively. If you achieve that you made a good purchase."

Frankfurt have already agreed terms with a possible successor for Trapp, according to Austrian paper Kurier, with Heinz Lindner set to join on a free transfer from Austria Vienna.

Lindner, who has played seven times for the Austrian national side, has already announced his departure from Austria.

"Several times I had the opportunity to make a move abroad and it never worked out. Now I am a free agent in my best years," Lindner is quoted by Bild.
