I've got no issues with this, in fact I think it is precisely the signing we need. Okay, so Vincent-Young might not have impressed a few years ago on a fortnight trial (and I've heard how we offered him a contract, but Colchester gave him a bigger contract to retain him). Either way, we're in a division below now and we clearly need quality in the full-back departments. Vincent-Young is considered a key player for Colchester United and looks to have the right blend of attacking and defensive attributes and quality. Currently at right-back, we've currently got Donacien who is not rated by the manager, is defensively okay - but lacks any initiative or ambition when he gets past the half-way line. Meanwhile, Emmanuel has squandered almost every opportunity the club has given him over the past few years, and last season he struggled to break into a lower mid-table Shrewsbury side. In fact, there are rumours that Emmanuel might be included in the deal.
No question that we also need to bring in another striker, but I think right-back is a key weakness for us and this looks like it will be a good move for us.
