Yeah, I checked it up. It wasn't even a cousin but still, it was a huge mistake and a good laugh. And yes, it was with Souness at Southampton.
It's a bit tough for me to keep in mind stories from English football. You don't get a lot of information about it over here. :-/
It was funny too though how Eintracht Frankfurt found out that their African top-striker was 5 years older than his passport said. So, suddenly, the player lost all his market value, thus the club risked its license because this value was used as a bank deposit. So, when a chance occurred, the club quickly sold the player to Leeds for over 3 million quid.
