Arsenal boss Arsene Wenger says he'll be watching the Manchester derby on Sunday.
Manchester City go to Manchester United as table leaders.
"Yes of course [they are the teams to catch]," Wenger told Arsenal Player.
"They have had good starts and have strong squads. You do not expect them to drop too many points but still I believe you could see that it is different for City and United in the Champions League. So everybody will drop points.
"It's very early to call Sunday's game a decider and it's amazing how quick people make conclusions. Let's not forget we have played eight games and we have 30 to go. Never has the championship been decided after nine games.
"It will be an interesting game to watch but overall whatever happens in this game the championship is still open. For everybody else in the Premier League the most interesting result would be a draw."
