Jan Kirchhoff only made seven Bundesliga appearances at Bayern Munich under Pep Guardiola, but he is full of praise for Guardiola in this interview with the Guardian. His words show the kind of impact that the Catalan has had on the club and players since joining Bayern in the summer of 2013.
In fact, if you listen to Kirchhoff tell it, the English Premier League will never be the same again after Guardiola joins Manchester City in the summer.
"What do you want - the polite answer or the honest answer? Honest? Pep Guardiola's going to win this league and change this league like you've never seen before. I'm totally sure. He's going to build one of the greatest teams at Manchester City and win the league without any trouble. You're going to see a totally different way of playing. It's one of the best situations English football's going to have for a long, long time."
Assessing the impact great club coaches can have on a national team, Kirchhoff was pretty blunt about the case for Germany's 2014 World Cup victory. I don't think we won the World Cup because of our unbelievable national head coach. I think we won it because of Guardiola and Klopp."
Kirchhoff cited the number of young, talented players getting the chance to play every day for Bayern under Guardiola and Borussia Dortmund under Jürgen Klopp as the key to the German's success.
"It depends how many English players Guardiola has at City," Kirchhoff said when asked about Guardiola's potential impact on the English national team. "But everyone who plays for him will tell you he makes you so much better. You understand this game in a totally different way."
How does Kirchhoff's current coach at Sunderland, Sam Allardyce, compare to Guardiola? "Pep's the best coach in the world for sure so I cannot say Sam's the best as well!" Kirchhoff continued, "But Sam's good. His treatment of players, the way he speaks to us, his video analysis, the way he prepares us for games is very good. I've had really bad coaches - but he's a really good coach."
With five matches left in their season, Sunderland are in 17th place, four points from safety.
