I'm perhaps in the minority, but I'm not too concerned just yet, solely based on the way our three signings have been handled so far.
I've mentioned it on here somewhere else, so apologies if I sound like a broken record, but Franco and Vigiroux were effectively signed out of nowhere. In Vig's case, the first proper rumours of him only started at lunchtime on Tuesday, and he was announced as a signing by 6pm. Similar with Franco (although those 24 hours felt like weeks), and Eom was a bit of an odd one as he was clearly signed on for a few days before we announced him.
I'm expecting any other signings in the next few weeks to be a similarly low-key affair, which I suppose does keep us mugs hooked online every day checking for updates.
After the opening day is when my concerns will be raised. We're noticably worse off than last season as it stands, and Middlesbrough will breeze to three points without at least three names in.
