Interesting. I wonder what that could mean. We will only get the second player if we manage to get the first?
It sounds to me like we really want Footballer A, but are also close to signing footballer B. The deal for B is almost done and if things don't work out with A it will be the only signing (other than Wood). However, even when the deal with B is complete they will continue to work on the deal for A, because they really want him. ("If there was an extra one it would be because we got the main target, something very special." = "If there was the signing of Footballer A it would be because he was the main target, something very special.")
