Jurgen Klopp said he had to make sure his Liverpool players did not switch off at half time in their 7-0 Champions League hammering of Spartak Moscow.
Liverpool led 3-0 at half time against the Russians, just as they did in their last Champions League game against Sevilla - who came back to draw 3-3.
The Reds made no such errors this time as they won Group E, with Klopp praising his team's focus as well as the football they played.
Speaking on BT Sport, Klopp said: 'I told the boys at half time, I don't like to talk too often about the obvious things, but a lot of people in the stadium will think 3-0, we have it already.
