How does he actually play? I can imagine with Xabi it's a possession based style.
Cant ignore the achievement he's pulled off with Leverkusen if they do go on to win the league.
I wouldn't say it's so possession-heavy.
Since Kloppo announced his departure, I have watched a few Leverkusen games. It's really very similar to our game. And above all very variable, sometimes dominating possession of the ball, sometimes standing deeper and countering.
Overall, they usually don't press quite as high as we do, they stand a little lower and are very compact.
Trying to get Xabi to be Jürgen's successor is a no-brainer.
