Borussia Dortmund turned to Liverpool's best-known sons The Beatles for inspiration as they wished their former coach Jurgen Klopp their best, after the 48-year-old was appointed the Reds' new manager.

"We heard the news today, oh boy! All the best at The Kop, Jurgen Klopp! All the best @LFC!," the Bundesliga club said in a tweet.

The short message is inspired by the lyrics of The Beatles' "A Day in the Life" -- it starts with the line: "I read in the news today, of boy" -- and came with a photo montage of Klopp running across the street like the cover of the Liverpool band's iconic Abbey Road.

The effort sparked an equally musical response from FC Liverpool: "Danke, @BVB! You'll Never Walk Alone."

Former Bayern coach Ottmar Hitzfeld said Klopp is a perfect fit for Liverpool and that he had arrived at the Premier League club at the right time.

"It will definitely be a long term project for him. He can really build on it and get a lot from it. With his emotional character and enthusiasm, he is a 100 percent good fit for Liverpool," Hitzfeld told Sky Sport News.

Hitzfeld added that Klopp would strengthen Liverpool as he would have a say in transfers.

Newspaper Die Welt warned Klopp, however, that he was "playing with his reputation" in accepting the job, noting the expectations placed on him by fans to revive the club that is languishing in 10th place.

But transforming Liverpool would require "time and patience".

"One can only hope that Klopp will be able to get results efficiently in the high-speed Premier League environment. Otherwise he could quickly squander his excellent reputation," warned Die Welt.
