My opinion is that there are gaps in our first team down our right hand side. A dominant, reliable centre half, a top right back and a right winger. Plus we seem to miss chances in games at key stages.
Put all that together and you get an inconsistent side who can be devastatingly brilliant one week, and average the next. If we can put out stupid mistakes (usually early in games or right at the end of them), take more chances when they arise, we have no reason to be worried about anything.
