Lewandowski expresses confidence in Szczesny's quick adaptation to life at Barcelona

The retired former Juventus goalkeeper made a surprising comeback to join Barca as a replacement for the injured Marc-Andre ter Stegen.

Lewandowski was key to the deal for his former Poland teammate and said from the nation's training camp: "Before leaving Juventus and retiring he told me that he would only continue playing if Barcelona called him.

"In this period in which he has rested he has regained freshness, and he will only need two weeks of training to get back in shape. He is calm and peaceful.

"I'm sure he will make a great contribution to the team. When a new player arrives, you have to introduce him to the club environment. The same goes for Wojciech, but with his experience and his attitude towards life, he will settle in very quickly."
