Everyone has an opinion, some I agree with and others I don't.
For me, if we sign no one else, do I expect us to be top 8 at the end of the season? Based on the performances so far (not results.), I don't think we will. This is just based on other teams - managers, current squads and players coming in. Whilst we have the Europa league to consider plus to be honest if our performances and results do improve, I don't believe it will be in the next couple of games.
I hope I'm wrong, but personally I think the is the season where we go back a step in terms of league position.
