The teams that defend well are as important as those that attack well. If you don't concede goals it is much easier to win but it is all about having balance.
I went a week to see Mourinho at training, and another week with Guardiola. I learned from the two, I took important things from both.
It's like Barcelona who have Messi. He decides games with his attacking play; Oblak resolves them with his saves.
What I'm trying to say is that within the styles, first, there's something clear: the style is given by the players on the roster.
He who brings a style to a club that can't carry it out, he is not a good manager, because he is attacking the club that hires him.
There are those who discredit a style or a way of playing and those who accept all the different styles.
I demand a lot and we look to improve, but I'm glad that Atleti are expected to be among the best every year.
VAR exposes everything. Before we didn't have the possibility of seeing some things that we now see. The referees are people who can be wrong as well.
Artificial pitches are just one more condition for us, like sun, wind or snow; we should be able to deal with such conditions.
Like I've always said, in football the most important thing is the quality of minutes not the quantity.
Football is wonderful because everyone can have an opinion and make judgements about what they think and see.
The hardest thing in life is reinventing yourself and staying at the top of your game, whilst the hardest thing in football is finding that club you want to stay at.
Diego Costa always gives us physical and moral strength. He is a very important player for the character he transmits to the team, and his potential as a football player.
Those who manage to keep the offensive and defensive balance are more successful. We search for balance in order to keep a stable level, which is the most difficult thing to do.
Every footballer has their own identity. A Uruguayan player is different to a Spanish player. A Portuguese player may be similar to a Spanish one, but not the same - and so on.
As a coach you need to choose the characteristics your players can contribute. I don't think it's a good thing for a coach to analyse his team by looking for something he sees in other teams. He has to pay close attention to the characteristics his team have, and make the most of those.
As a player, you can be more spontaneous and instinctive, but now as a coach I have to find a psychological balance within the team.
Defeats are always tough, whatever you have lost, and they affect me the same way they affect anyone who loses a match - no more or less.
Whenever a fellow coach is sacked it is not good for any of us - it hurts. You just have to accept it because it is part of the game.
At some point, I would like to coach Argentina, but I have to improve as a coach. I would like to do it in the final stretch of my career.
Maradona and Messi played in different times and in different positions. Messi is much more a striker, Diego was all over the entire pitch. They are two extraordinary players.
