I think a lot of the worries from the fans comes from the sudden uncertainty of the performances. Under Mancini whilst we had become predictble and possibly a little boring we were a very hard team to breakdown and score against, hence a very hard team to beat. After the last 2 games that is now no longer the case, or at least appears to be no longer the case. That confidence has gone. As the confidence of some of our players appears to have gone. 'Fragile' it has been described as. I would say more brittle again this is worrying.
As a number of posters have already pointed out if we had played some 'top' or better teams who have top class strikers we could very well be sitting on just 3 points right now. Our defence which was once a fortress now looks like a colander and that is very unnerving.
Whilst some posters on here show admirable blind faith and positivity a lot of other are basing their judgments on what they have seen in the last 2 games and they are worried with what they see. We will have a much better idea of how the season will pan out after the next 2 games. We need a minimum of 4 points from those 2 games otherwise the worries will start to become more pronounced and 4 points from the next 2 games is not going to be easy by any stretch of the imagination. It looks like it is going to be an interesting season.
