The Gunners went seven points clear at the top of the Premier League table after beating Brighton.
Mikel Arteta believes Arsenal need more improvement despite their impressive victory over Brighton.
Everton held Manchester City to a 1-1 draw, providing a chance for the Gunners to go seven points clear at the top of the table by beating the Seagulls.
Arteta’s men claimed the three points with a brilliant attacking display, defeating Brighton 4-2. The Gunners got one step closer to the Premier League title as they hope to lift their first league trophy since 2004.
But the Spaniard insists his side should focus on improving their displays instead of getting excited by the title prospect.
“It’s still a long run to go,” the Arsenal boss said after the Brighton match.
“My excitement comes from going into the dressing room when the players are talking about what they should have done better today.
“That means that they know that we can still play better and be better and against Newcastle we have to be better.”
Speaking to BBC Sport, he added: “We knew the result [of the Manchester City game], but the boost is we have to come here and win, and to do that we have to perform at the highest level in this league.
“Tonight we had to have a big performance to win against a really good Brighton side. We had to dig in as well.
“[We have] a lot of things to improve, especially in defending moments. We still have room to improve.”
