Former ​Bayern Munich midfielder Xabi Alonso has revealed that he joined the Bavarian giants after leaving ​Real Madrid in an attempt to find out the secrets of Pep Guardiola. 

The Basque footballer tied up with the Catalan in 2014 and stayed in Germany for three seasons before retiring from the game.Unlike some of the best players in the game, Alonso managed to stay on top till he decided to hang up his boots. 

He was an integral player in Die Roten's system – where he was often played as a libero in the heart of a three-man defence by Guardiola – and is yet to be replaced properly by the German giants.

He played 117 times for them and won three ​Bundesliga titles in the process. Now, he has revealed why he joined Bayern in the first place.

"I was so curious to find out [Guardiola's] secrets. He has a relentless natural enthusiasm. Football seasons are long but right until the very end, Pep never seemed to be tired," he was quoted by AS.

He was also full of praise for Jurgen Klopp, claiming that he didn’t enjoy playing against Klopp’s team.

"He was alert, always ready. For the players, maybe this gave us an extra few metres in our legs when it mattered most. I didn't enjoy playing against them because they made it so intense, you'd almost break.

"It was like he wanted you to be in a cage. He wanted to trap you. There was an organised pressure. I was under pressure all the time. I enjoyed the mood around those games because they were so important but the challenge of beating Dortmund was immense," he concluded.
