I think we’re definitely going to see some of these, we have seen some already during preseason. Blind’s move is most obvious because he’s played there already on multiple occasions and would arguably be one of the best options at the club.
Wilshere’s move to right attacking-mid is probably the next best bet due to the number of options currently ahead of him in the middle. I actually wouldn’t mind seeing this at all.
Most of the others are either weird or, if they occurred already, just temporary and not permanent solutions. Van Gaal has said that Januzaj can play as a striker but we’ll see it when we see it. I don’t see that happening for Ross Barkley, Kurt Zouma should play central defense, Seamus Coleman is good enough at right back, Fernando may be even worse at centreback and Eric Dier would be weird in the middle.
Kolo Toure would actually be going back to the very first position he played for Arsenal so that may be possible. Doubtful though.
