Speaking about 23-year-old Kiwior’s first start for Arsenal, Arteta said: “He looked ready, he looked fresh.
“He looked really determined, he’s been getting better and better every single day. Not only training but his interaction, his language, he is more settled and is a player that I really like which is why we signed him.
“He’s got the potential at his age to be great and I think he had a big task against the players he had to face today and I think he did really well.”
But while £21million January signing Kiwior impressed against Chelsea, a run of seven games without a clean sheet will concern Arteta.
