Liverpool boss Jurgen Klopp has been able to laugh off his health scare this week.

The German coach was advised by club doctors to ­undergo ­medical tests, after ­feeling unwell following a return flight from South Africa. But Klopp had a message for Reds fans as he returned to work.

“I am really completely fine. I told the players the doctor said the only thing that can kill me is if we lose football games," he said with a smile.

“That's it. It was nothing. It is not that someone should think I have to go back into hospital ­tomorrow.

“It was not a marketing thing by Liverpool! I came into the hospital and, when I passed the first few people, I saw a security man go into his walkie talkie, 'Klopp's in hospital! Did you see him?'"

He was back to oversee training on Thursday, and he ­insisted he is in perfect health, ­despite the scare. Klopp said: “I went there and they said, 'OK, all good'.

“For this they need a little bit of time, they have a lot of ­machines. But I knew from the first ­second I had nothing – ­unfortunately I was the only one. Afterwards ­everybody knew it."
