I suppose so, but it's not as if they've represented particularly esteemed clubs, more fringe clubs was more my point I guess. But yes it is very unusual.
This sounds like a quiz question for me - Which English club(s) in 2016 had 3 goalkeepers on it's books to have played Champions League football? There cant be many surely - have Man Utd with De Gea, Valdes and Romero? Not sure about the last one.
"Which English club has three goalkeepers who have played Champions League football for non-English clubs?"
It's not a good quiz question then. Too many grey areas. Let's stick to football trivia questions like the MACKEREL one !
