Arsenal manager Mikel Arteta admits Bukayo Saka is struggling after a big summer.
The 20-year-old played an instrumental role in England's run to the Euro 2020 final.
Saka failed to make an impact in the win over Burnley on Saturday, but Arteta insists struggling is "part of his development".
Speaking to Football.London about Saka, the Spaniard said: "I think there are still things to improve there, but he is trying hard.
"He is another one who struggled in the final minutes.
"But it's great that he's able to suffer and somehow come through that and manage these difficulties and adversities during games where it is not really going for him."
Arteta added: "That is part of football. He had parts where he was brilliant and then he struggled and then he was brilliant again.
"That is better than being brilliant and then to struggle, struggle and struggle. So it's part of his development and I'm really happy with him."
