A knock on the door from someone you’re not too keen on being interrupted by can come at the most frustrating of times.
As you’re sitting down for dinner, about to start a film or, all too commonly, as you’re addressing the world’s media following a Champions League semi-final win.
Liverpool manager Jurgen Klopp was speaking to journalists after his side beat Roma 5-2 in the first leg of their Champions League semi-final at Anfield.
A brilliant brace from Mohamed Salah, as well as two goals from Roberto Firmino and one from Sadio Mane had the Reds five in front before a defensive mistake and a harsh penalty saw the Romans claw back two away goals.
European press conferences can be particularly convoluted at the best of times, with a translator having to relay everything one manager says to those reporters covering the opposition.
That same translator, however, could well come in handy if you lose your trail of though following an interruption halfway through proceedings.
