Real Madrid midfielder Toni Kroos insists he values the influence of Manchester City boss Pep Guardiola.

Kroos worked with Guardiola at Bayern Munich.

"During my year with Pep Guardiola I took a big step forward," said the Germany international.

"Jupp (Heynckes) was the most important coach in the early stages of my career, both in Leverkusen and Munich. He saw me as a central player in his system, where my style of play fit perfectly."

On Real, Kroos added: "When you move to a top team abroad and affirm your position in the team, you've taken another step forward."
