Walcott believes Arteta will not be pleased with Eze following Arsenal's 3-0 victory over Coventry on Friday night.

The reigning Premier League champions made an excellent start to the new season, with goals from Havertz, Saka, and Ødegaard securing the win at the Emirates Stadium.

Eze started the match as a substitute, coming on with 14 minutes remaining to replace Tsolis.

However, Walcott believes Eze's attempt at a long-range free-kick, which went well over the bar near the end of the game, probably did not impress Arteta. He stated that these "details" will influence the Arsenal manager's team selection throughout the season.

Walcott said in an interview with Premier League Productions: "For this team, it's really important to build a winning mentality because, once you get into that habit, it's very difficult for opponents to deal with."

"When you look at Coventry, they sometimes didn't know what to do; there were too many gaps and spaces on the field. When Arsenal play freely, I want to see more of that. I feel Arsenal still have many gears to go up, which is a good thing."

"Even when substitutes come on, it's their chance to show Mikel, 'Don't forget about me.' I feel some players could have done more after coming on as substitutes, but it's the first game of the season, so we should show them some understanding."

"This is just a reminder to those who didn't start: the squad depth is strong. If you want to get into the starting eleven, Mikel will be assessing whether you meet the required standards."

"Eze's last shot... I'm not sure Arteta will be happy. I know it's a small thing, but if he's going to go through the season with these players, he'll be looking at these details from every player, and that's a warning sign."

Walcott also praised Tsolis' performance. It was Tsolis' first Premier League appearance for Arsenal since his £34 million move from Club Brugge this summer.

Walcott said: "I really like him; he reminds me of Alexis Sanchez."

"The reason I say that is that his first touch after receiving the ball is positive, and his first instinct is to go forward and attack the full-back. Sanchez always gave full-backs a headache, and Tsolis wearing the number 17 also reminds me of him. I know Sanchez switched to number 7 after Tomas Rosicky left."

"However, the way he moves with the ball is very special. He looks very light on his feet on the pitch, and his teammates are willing to keep passing him the ball. I think you can see his confidence growing. He's a bit faster than Trossard, so he's a bit like a combination of Trossard and Sanchez."

"Overall, I'm very impressed with him. I believe he will perform even better once his physical condition improves further and his teammates have a better understanding of his style of play. So far, I like everything I've seen; it's really very impressive."
