Jurgen Klopp is an incredible manager. He's won almost everything there is to win in football during his time with Borussia Dortmund and Liverpool.
But he's also an extremely emotional and caring character.
And he's shown that side to him with a brilliant letter he sent to an 11-year-old boy.
Lewis Balfe, from Maidenhead, was worried about making the step up from primary school.
Balfe probably wasn't expecting a reply. After all, Klopp is a very busy man.
However, the German manager took time out of his day to write back.
The letter read: "Hello Lewis, can I start by telling you a secret? I get nervous.
"To be totally honest I would be worried if I did not get nervous because when it happens it gives me the chance to turn the energy into something positive.
"I know it might be strange for a boy of your age to think that the Liverpool manager can feel the way that you do, but I do.
"...you do not need to worry about bad things happening.
"As you know, I lost more than a fair few finals and this isn't a good feeling, but with the help of family and friends I kept going and in the end we were able to enjoy some really good times.
"If I had dwelled on the bad moments, I know that this would not have been possible, so please be positive about yourself and look forward to the brilliant time that I know that you will have growing up."
Read the full letter below:
Lewis' mum, Milena, spoke to the Liverpool Echo about the letter her son received.
"Lewis was quite overwhelmed, and in complete shock, it was a personal letter back from Klopp," she said.
"It's lovely of him, really nice.
"We went straight to the shop to get a frame as Lewis was worried about it getting damaged and it's now on is desk in his bedroom."
Liverpool fans loved Klopp's letter.
Pure class from Klopp. He's given a fan a memento he will no doubt hold on to for the rest of his life.
