Defeat in the Champions League at Real Madrid was played at Madrid's 6,000-seat Di Stefano Stadium, inside their Valdebebas training base, rather than their famous Santiago Bernabeu home.
Afterwards, Klopp complained: "This here tonight was really strange because it was a difficult situation in the stadium, but Anfield is at least a proper stadium and that will be good for us."
In reaction, Eleven Force, the company that designed the ground, decided to send him a memento from his visit.
"We know that Jurgen is a guy with a great sense of humour and he sure welcomes it with good humour," Jose Guerrero, head of the company, said.
“In addition, we will also send him a Wanda (Metropolitan) to serve as a souvenir of his last Champions won (in 2019) and a Son Moix for when, as he commented, they decide to come and train Real Mallorca."
