SpVgg Unterhaching striker Felix Schroter believes Pep Guardiola has transformed the career of former Schalke teammate Leroy Sane.

The pair played together at Schalke before Sane left for Manchester City.

Schroter recalled to BILD: "It was very, very clear that he was a very special player. I always expected it, that he makes the breakthrough. But I did not expect him to shoot through the ceiling in such a short time. He has developed in all respects.

"If you train under a coach like Pep Guardiola, that almost happens automatically.

"In the past he might not always have the focus and was a bit distracted in Schalke at times. Under Guardiola he has now developed the greed to want to get better and better. His passing game, his moves towards the goal - now everything is much more purposeful with him."
