"I'll be honest. I was frustrated, I wasn't playing, I didn't play a lot of the games", said Walcott. "We need to improve this". I am then going to choose the best first 11.
"We obviously played Arsenal two weeks after I moved [losing 5-1], and it still felt like I was a little bit there, because it was too soon". I keep calm. My chance will come.
Sarri has also vastly improved the performances of the players he inherited. "But I actually think the Petr Cech I have seen in these first five or six games looks like the Petr Cech I remember at Chelsea in terms of the saves he is making and his starting positions".
Cech has kept his place despite an indifferent start to the campaign, which has been blighted by suggestions he is not suited to Emery's approach of playing out from the back, something Leno was routinely asked to do at Leverkusen.
"But I think it's all about having that self-belief, that right mentality".
WITH European football now in full flow, the English Premier League's "Super Sunday" is set to revert to "Europa League catch-up" as the sides that missed out on this season's Champions League adapt to Thursday night trips around the continent.
"We have fun together".
"The Premier League is very important because I think it is the first competition of importance for us, because that gives us the big credibility on this season", he said. Of course, he is a big personality. "He had a big career and is still a very good goalkeeper -it is very good to work with him and for my development it is very good to have the competition with him".
Eight permanent managers - Howard Kendall, twice - before current incumbent Marco Silva have tried and failed to finish above the Gunners since the inauguration of the Premier League back in 1992/93, but to no avail, with the North London club bagging three titles in that time.
Leno is more at home with the ball at his feet, but admits a goalkeeper needs to know when it is possible to do so. I had great times but I feel like I'm going to have even greater times here, I really do.
"We want to play because we have the players to play from the back to have more space in the opposite 18-yard box".
