Arsenal boss Mikel Arteta is delighted with the progress of Jakub Kiwior.
The young Pole has won consecutive games in his first two starts for the Gunners.
Arteta said: "He's been getting better and better every single day, not only in training but his interaction and his language.
"He's more settled and he's a player that I really like, that's why I signed him.
"He has the potential at his age to be great and he had a big task against the players he had to face today, and I think he did really well."
