I have a pretty good idea of what makes NBA players great - especially at the different positions, and where the biggest problems lie that you have to address in defending those people.
If I watch big games like the Champions League on TV then I'm definitely watching what different centre-backs are doing in certain situations.
The league has changed in so many ways. There are no point guards anymore, there are no centers anymore; it's all positionless basketball.
What I always do is just look at the players, look at the best 11 they can put on the pitch.
For me, there are no 'between players' in football. For me, there are clear positions and clear characteristics for all players.
Certain players need twice the recovery time of others because they run much more - not because they put in more effort but because they're playing different positions.
You go to the draft board and think, 'Here's a nose tackle. Who needs a nose tackle?' Well, eight teams in front of you need a nose tackle, and there's two nose tackles. It's something you have to figure out where you can get the players to play in your system.
Everybody says Steve McManaman played on the left for me in Euro 96 but he never played on the left. The one time he did play on the left was against Switzerland.
We are trying to get away from those traditional centre, power forward type things.
It's not science; it's common sense: it's playing the right players in the right positions for the style of football you want to implement in a specific game.
We can be tackled but referees are there to police dangerous challenges. Forwards are protected by the laws of the game and the way it's played, while defenders and midfielders have to throw themselves about a bit more.
I've played all over, to be honest. Centre-half, defensive midfield, attacking midfield.
Whenever you are coaching, you are trying to get the most balanced team that you can: balance between defense, offense, and rebounding.
It's true that Coutinho played on the centre because sometimes Messi likes playing on the right side. If that happens, we have to readjust a bit.
You need two or three players who can do that - play behind the striker, on the right wing, the left wing... striker, maybe. If we have those, it's good for the team.
