He said: 'To explain how difficult it is to prepare for a game like this is hard.
"Tough game, always tough when we come here, but we kept the goals out and I knew if we kept going we'd get a chance at goal", the defender said on LFC TV. One session with a specific demands of set-pieces. It's hard. You need to work on your own set-pieces and you need to focus on the specific quality of the opponent.
The German has enjoyed success by switching formation from 4-3-3 to 4-2-3-1 in recent weeks, with Xherdan Shaqiri coming in on the right and Mohamed Salah starting as the main striker, allowing Roberto Firmino to drop into the No.10 role. It's so hard. And then Capoue and Doucoure picking up all the balls and playing it direct again in this direction.
"We tried to do our best but after scoring the first goal, with more spaces, they are very unsafe".
We had Trent and Dejan at 100 per cent, so we didn't have to make a decision. So, 3-0, it couldn't have been better.
Klopp also confirmed Daniel Sturridge is available to face Watford and has not been affected by an FA charge over alleged breaches of betting rules, with captain Jordan Henderson also in contention to be selected. "You play in a defensive-midfield situation and I don't know how many challenges Hendo had today or situations where he had to be closing the player or space". Twice he was there with a hand and made a tactical foul. It was clear he could be rested and can recover more, and then he is ready for Wednesday again. The only not-so-nice thing is that he can not play against Everton but that's already accepted.
Liverpool unbeaten in their opening 13 PL matches for the first time since 2007-08. "The 33 points are brilliant. Outstanding. The goal difference is really good", Klopp added.
Mane, who has scored six league goals this season, signed a new contract with the Anfield club on Thursday, following in the footsteps of his fellow attackers Mo Salah and Roberto Firmino who agreed long term deals in the past year. But the season is not finished and it doesn't bring us anything.
There's a real feel good factor around Liverpool at the moment, but that will need to translate into silverware sooner rather than later. "I love the club and I want to win something here". It's not usual you have these two things in your mind, usually you only think about winning.
"I think they were both yellow cards", he said. "Today they did a really good job, and I like this game a lot because it was so hard".
Obviously we can't be sure but let's see what happens when they inevitably meet in the Champions League now! Controlling it and staying in that mode, being positive, that's new for us.
"It may be better for him to leave within a season or two if Liverpool doesn't win any titles", he said. It is not fair to compare it with other games. The last games he played were pretty much all good or better.
"To extend a contract is more than a signing, it is a statement". He radiates joy and I think this is reflected in his performances and impact on the pitch. I'm happy about that.
