I somehow managed to solve this wall and I don't really know how. Apart from the birds, none of my connections matched yours. For one, the begin and end in the same letter group are all Scottish club but this wasn't accepted as an answer. Though still a vaild connection. The 'red' group I said were all winners of European trophies and the Moyes group could be connected in many ways. All valid. Nice idea, but there are simply too many ways to form different yet equally valid connections within this wall.
