A good signing? Leaving aside his first name, which sends shivers down the spine, and the fact that his career to date has been marked by underachievement, I think Richardson fits the bill nicely. He is naturally left footed, he has pace and he has a wicked shot on him. Of course, 19 career league goals does not scream quality but there has always been a sense that Richardson may explode into life and look a very good player - and returning to the West Ham fold with Allardyce kicking his arse may be just what the guy needs.
Importantly, Richardson is a square peg to fit a square hole and, the injury prone and mediocre Taylor apart, we haven't had one of those on the left of midfield since Etherington was switched to the right by Zola and then sold! With Vaz Te on the other flank and Cole down the middle, there would be a decent shape to the side going forward, and Richardson could also help out McCartney defensively.
A thumbs up from me if it happens!
