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.
Despite winning the group, Liverpool could face some major teams in the last 16, including Real Madrid, Bayern Munich and Juventus.
Klopp however is unconcerned who Liverpool play, and is just happy they are in the knockouts for only the second time in nine years.
He said: 'We just wanted to go to the next round, I don't mind too much. Usually I get Real Madrid, so we will see what happens this time.
