ペトル・チェフ
Leno made his debut for Arsenal in the 4–2 victory over Vorskla Poltava in the Europa League. Leno made his Premier League debut in the 2–0 home victory over Watford, replacing regular goalkeeper Petr Čech, who picked up an injury in the first-half. His performance was praised by head-coach Unai Emery, who said "He is working very well with the goalkeeping coaches. I spoke with him and said the most important thing is when the team needs him to help us, to be prepared. He did that on Wednesday and today also – and against Vorskla. We have three very good goalkeepers. Petr Čech, his performances for us have been very important and his experience. Leno can learn by staying near with Petr Čech every day. I am very happy with him. He has waited for his moment and it's arriving."
