Arjen Robben says he has learned more from Pep Guardiola than any other previous coach, revealing that the Bayern Munich boss is so intent on helping his players that he would be willing to offer advice at three o'clock in the morning!

The Netherlands internatonal has played under the likes of Jose Mourinho, Louis van Gaal, Jupp Heynckes and Guus Hiddink during a club career that has taken in spells at super-clubs such as Chelsea and Real Madrid.

However, Robben believes that his current coach is a class apart, admitting that he is in awe of Guardiola's intelligence, tactical acumen and dedication to his profession.

“When I started working with Pep 18 months ago I noticed how he goes much deeper into football,” the 31-year-old told The Guardian. “His intelligence is obvious. 

"Tactically, he’s one of the best in the world and under him I have made more steps in my development. I’ve come quite a long way these last 18 months.
