I remember reading an interview with him where he was very unflattering about his time at the club so maybe that played a role in it.
Personally I found him a strange keeper...could make awful mistakes but on his day he could be world class.
I was at the Spurs Arsenal match in April 2010, where Danny Rose scored in our 2-1 win. We were 2 up when RVP came on with about 25 mins to play.
RVP took a brilliant free kick which, somehow, Gomes saved. That was followed by RVP catching the ball on his chest and turning and volleying a shot to the top corner which, again Gomes somehow saved. But his best save was from a point blank range header by Judas which he turned onto the cross bar. I think it was the best goalkeeping performance I have seen live since I first went to a match in the late 70s.
All in all I remember him fondly and am pleased he is doing so well at Watford
