To play at the highest level requires tremendous effort, concentration and above all, never giving up.

If you are successful, then it is only human that you are sometimes a bit saturated. You might also lose that hunger which means that others who are more ambitious will knock you off your pedestal.

Without planning there will be no success.

The role of a coach is varied. We have many tasks. To be a visionary that always looks a little bit towards the future: How should the team develop? How should it play at a tournament? Of course you also have to be the contact person for the players, where social competence also plays a role.

I tell my team: if we win the ball, I want to see the ball in the goal in eight seconds. That's my philosophy.

If a player has good technique and a good basic speed, but is slow in the head, this may reduce his value to the team.

When we play with three at the back, we need active players, who tie up the opposition and play passes forward.

People always think that somehow they know everything, can do everything.

Sometimes, as a coach, you have to somehow accept personal disappointments.

Neuer is of course the best goalkeeper in the world.

Cristiano Ronaldo is sensational, a very good professional, an incredible goalscoring machine for many years, but Messi is the most complete player I have seen.

I don't agree with people saying that I am immune to advice or cannot admit when I make a mistake.

Those who know me are aware that I stand by my mistakes or non-working strategies.

For me, it is utterly incomprehensible how people share their private life, from truly confidential and intimate things, indiscriminately with thousands or even millions of people.

I can see exactly why Liverpool want Klopp.

You cannot let him out of your sight, literally. You've always got to ask: 'what's Ronaldo doing, where is Ronaldo?'

I said to Gotze: 'OK, show the world you are better than Messi and can decide the World Cup.' I told him that. I always had a good feeling about Gotze.

Gotze is a miracle boy, a boy wonder. He can play any position up front.

I know lots of Korean players, Heung-Min Son from Tottenham Hotspur of course, there are also lots in the Bundesliga. They have a great mentality and are very quick.

Real Madrid are an interesting club for any manager.

Everyone who knows us knows how we always encourage players to speak out, to be open and honest, to be critical. These things are very important to us.

You need superhuman performances at the World Cup.

As a coach, of course I favour competition.

One can not win titles with result-orientated football anymore and this has been clear to me since 2008.

Even before the World Cup in 2010 I had said that there were no world champions who aim to stifle the opposition's play and somehow hope to win. These teams do not go far.

If players from our national team are playing in the Bundesliga, it for me shows that it is at least as strong and attractive as the Premier League or La Liga.

There are things you can learn about certain players while watching them in action in a friendly.

Every player has his own strengths and weaknesses and has to be integrated into a team.

Everybody wants to have the ball and be perfect with it.

You can learn a lot from setbacks.

I am coach of the Germany national team and there are not many jobs in the world which are better than this.

I don't say anything about referees' decisions, you have to accept them.

For us to reach the Euro 2008 final was a success.

You need to receive the ball and be assertive with it.

You need to be able to deal with pressure while on the ball and not keep giving it away in easy situations.

I have faith in all my players.

I would not deny that to work as a club coach could be fun.

The end of a tournament is a good time to pause.

The cognitive development of the players is enormously important, as well as social competence and character values such as discipline and teamwork.

Mesut Ozil, a Mario Gotze, a Mats Hummels, a Holger Badstuber, and so on - they are very mature even in their younger years.

Intelligent players are receptive and capable of implementation.

Every game brings important insights.

German virtues are now about technically good players playing attacking football.

If you have a good product, like football, you should also think about limiting it to keep the quality high.

You have to be careful that you do not overdo things with too many games, because the quality must not suffer. Fans would then also turn away and the interest would subside.

World Cups and European Championships should feature the best teams. When you keep increasing the number of teams, you dilute the quality.

If a player is 20 or 21 and sits on the bench for two or three years, I don't know if that's useful.

Pep Guardiola was very good for the Bundesliga.

To whistle your own player at one time or another, even before kick-off, I don't think is fair. It doesn't help the player carry on, so it doesn't help the team.

Stefan Kiessling is a striker who has put in very good performances in the Bundesliga over the years.
