Arsenal hero Jens Lehmann has given his seal of approval to Wojcieh Szczesny.
The 21-year-old Pole is now No.1 for club and country.
Lehmann told the Sunday Mirror: "He has improved a lot. I worked with him and I trained with him.
"He organises his defence and he has a great presence. And he will get even better with experience. He has great natural ability."
