Early days yet, but Leeds and Middlesbrough have been undeniably impressive.
I also think that Forest have a very good chance of the playoffs. They have only won one, but actually haven't lost. A good performance against Newcastle last night, although these cup-games can be deceptive.
I wouldn't be surprised if those three develop into the ones to beat.
As always, a lot depends on how you survive the inevitable "bad run", and how quickly you recover from it.
Any other thoughts about the top six? Swansea? Derby? Villa?
I wouldn't discount WBA either.
It already looks as if it is going to very difficult to beat ANYBODY! Our main priority now is to start converting more chances. Probably the same for Forest.
