Mikel Arteta believes the Premier League table will start to take shape after 10 games.
Arsenal returned to the top of the Premier League on Sunday after Jack Wilshere's second-half strike secured a point away to West Bromwich Albion.
That's what makes this league the most entertaining in Europe so we know how tough it's going to beMikel Arteta
But the Spanish midfielder said it will take a little longer for teams to get a better idea of what "level" they are at this season.
"After 10 games most of the teams have played against most of the teams," Arteta told Arsenal Player. "You know where you are and you know your level. You have played against teams at the top and teams at the bottom as well. But at the moment the league looks good.
"It's going to be tough. There are five or six teams challenging to win it so you are not depending on one or two results.
"That's what makes this league the most entertaining in Europe so we know how tough it's going to be. But we are on a good run and we are confident with the players we have."
Arteta has started the Gunners' last two games after missing the start of the season with a thigh injury and the 31-year-old said he is delighted to be back.
"It was frustrating to be out of the side because I worked so hard in pre-season and then I got injured. Psychologically it was hard to take. But I worked hard because they weren't expecting me back for six to eight weeks and I made it back in five so I was really happy."Copyright 2016 The Arsenal Football Club plc.
