Bernd Leno will become the second German goalkeeper to play for us after joining from Bayer Leverkusen - and he admits he learnt some key lessons from his predecessor.

Having grown up idolising Jens Lehmann, Leno was thrilled to have the chance to work alongside him at the start of his career and says the experience was invaluable.

"When I was a child, Iker Casillas was always my idol, but when I was at Stuttgart, there were many players, like Timo Hildebrand and Jens Lehmann," Leno told Arsenal Player.

"I watched many of Jens’ training sessions to learn from him. I had some training sessions with him when I was very young, about 16 or 17 years old.

"Jens was around 40 years old and for me it was very exciting. He was so concentrated, so professional and that’s the mentality that you need as a professional goalkeeper."
