Unai Emery insists Arsenal still have much room for improvement despite winning their last nine games in all competitions.
Having lost their opening two games of the season under Emery against Man City and Chelsea, Arsenal are now in a fine run of form going into their Monday Night Football clash with Leicester at The Emirates, live on Sky Sports Premier League from 7pm.
But the Spaniard, who took over from Arsene Wenger in the summer, says he would like to see more control in Arsenal's play, and says every team can cause them problems.
In an exclusive interview with Sky Sports, Emery said: "Not a surprise. We are doing the things better in our way, but we also need to continue improving, getting better, because we won more consecutive matches but we also need to improve our control in the game.
"Every match, every team has solutions and quality to give us problems, and Leicester is the same. Our success every day is work, continuing to work hard to improve these things."
Reflecting on his first four months in England after stints in Spain and France, Emery recognises the Premier League is extremely competitive, and says his side are close to matching the top sides but must keep working hard.
"It's competition. Here there are more competitive teams, and with the best players at Man City and Chelsea and Liverpool and Tottenham.
"Can we stay with them in the table? We are close but in two matches against them we lost and our challenge is to continue to find a performance for these different [games] to get closer to beating them."
