The most important thing however is the money. What use would it be to us, to have a a mighty stadium but a useless team, because we couldn't afford anything better?

The Olympic stadium may have been built only in the early 1970s but it was clear for a long time it had no future. For many reasons it is not good enough for modern football and today's fans.

What FC Bayern has become is thanks to Gerd Mueller.

Messi is a genius. He has everything. When I watch him, I see a player who is very, very skilful, very clever and his left foot is like Diego Maradona's.

The one who’s really, really impressed me is Benedikt Höwedes because he’s playing out of position. He’s never played at left back before in his life but he’s having a first-rate World Cup. So, the most astonishing player for me is Höwedes.

It is not the strong one that wins, the one that wins is strong.

The trouble for today's footballers is they have too many distractions. We used to get our old players coming to watch training with football magazines in their hands. Now, more often than not, they are checking the share prices.
