Jurgen Klopp may seem like one of the smiliest, friendliest football managers around, but the German manager still won't let journalists sneak silly questions into his press conferences.
Klopp met the British media for just the third time since arriving at Anfield as he held his standard pre-match press conference ahead of Thursday's Europa League tie against Ruin Kazan.
Lucas Leiva was chosen to join the new gaffer and was the focus of attention for one unfortunate journalist, who just wanted to know what the former Borussia Dortmund boss was like "as a manager and also as a man".

Lucas immediately started squirming in his seat as if it was his first day at school. Of course he could not answer the question; Klopp was sitting right next to him.
Luckily, the Brazilian midfielder was rescued by Klopp, who patted him on the back before launching a warning shot at the man who asked the question.
Klopp said: "It's nothing we have to talk about, we talk about the game. It's been 11 days. If he thinks I'm an idiot he cannot say. So why ask him that. It's a self-answering question"
"You don't have to answer," he told Lucas.

The dark side
Klopp and his iconic smile make it seem like he is as harmless as a tortoise on its back, but the 48-year-old has certainly shown a tendency to, well, go mental when the situation calls for it.
Who can forget the poor fourth official who had to deal with Klopp and his angry, angry face after Napoli scored in a Champions League game in 2013?
So, be warned, journalists of the Premier League. Klopp may float like a butterfly, but he certainly has the capabilities to sting like a bee.
