Mark Warburton will leave the club despite taking them to the play-offs

But the Bees were unsuccessful and continue their search for a manager

Brentford were keen to speak to him about taking over at Griffin Park

Brentford have failed with an audacious approach for Borussia Dortmund manager Jurgen Klopp.

Klopp, who led the Bundesliga side to a Champions League final and two domestic titles during his reign, will leave the German giants next month.

Championship club Brentford had hoped to lure him to England to replace the outgoing Mark Warburton but were knocked back.

Dortmund fans thanked Klopp for his service to the club as he prepares to leave next month

The odds on Klopp taking over at Griffin Park plummeted to 4-1 on the same day Dortmund's fans said a fond farewell during the final league game of his seven-year tenure.

Sportsmail also understands Brentford were keen to speak to Thomas Tuchel before he agreed to succeed Klopp at the Westfalen.

The Bees are searching for a new boss after announcing back in February that Warburton would leave the club at the end of the season, despite the club challenging for promotion to the Barclays Premier League.

Brentford reached the Championship play-offs but were beaten by Middlesbrough over two legs

Brentford reached the end-of-season play-offs but were soundly beaten by Middlesbrough who take on Norwich in Monday's final at Wembley.

Gianfranco Zola and Paco Jemez are the favourites to take over at the west London club while Klopp is 2/1 to take over at Liverpool should Brendan Rodgers leave.

The 47-year-old has also been linked with a move to Turkish side Fenerbahce and to West Ham, should they dispense with the services of Sam Allardyce at the end of the season.
