Chelsea being on the 3rd, Arsenal being on the 4th and Nottingham Forest being on the 5th is probably the biggest surprise of this season so far. Let's see how it shapes going forward. I really want to see Nottingham Forest be one of the top four teams. Chelsea and Arsenal both are not playing very well, they have only one win each in the last 5 matches. So I think they do have a chance 
The most suprise for me there is Chelsea as they didn't look like a team that could be in the top 4 position this season although they shouldn't celebrate yet as they're on th same points with others below them and one game lost alway from falling off the top 10 position as other teams are just one point below while others are two and three. The table position is going to be different after the international break as players will return back having injuries or feeling tired and they can't perform as they use to do. making other teams to have the opportunity to go up the table.
