Liverpool manager Jurgen Klopp was visibly delighted after his side eased past Everton on Wednesday night.
The Reds are enjoying one of their best spells of the season as they moved up to 7th in the table.
The German expects a tough game on Saturday against Newcastle United as his side continues to fight for a Top Four finish.
"The first half, it was a derby so it was a little bit too wild for a normal football game," Klopp explained.
"It's a derby, so you have to accept it, and it's not about a passing game or things like this. We had the moments where we passed and could have done better, but we lost a little bit of patience in our own moments.
"We knew about their defending style and we wanted to have a pretty offensive formation, but if you have a formation like this you can't take the risk – you need to play the right pass and not the pass you want.
"We forced a few things a little bit too early. We had the movements and it was OK, but it is not allowed to use all of these movements, especially behind the line. We tried it a little bit too often and that's what we told the boys at half-time.
"Of course, the two goals were in a perfect moment [before half-time]. Then second half, it changed completely with the red card and it changed completely [again] with then the next change when [John] Stones had to come off [for Everton].
"That was really not easy for Everton. We are in a good moment, we played football, we created chances and we could have scored a few more.
"We did well, but usually after a 4-0 I don't know how to keep my smile off my face, but today it is pretty easy to be honest [after the injury to Origi].
"It is like it is, we have to take it, see what happens and in three days we have the next game – a real battle. I saw Newcastle yesterday and they played very physically, it was a little bit like a derby [against Manchester City].
"They will fight for the league and we have to respect this, so we will have to see who we can bring in. The last 20 minutes, maybe 30, were not too intensive in this game today, so we will see tomorrow.
"It was good for us, good result, clean sheet and four goals. All the other teams in the table above us won too, so nothing has happened, but we can't change this – we have to win as often as possible."
