The following link:http://www.waterpolodevelopmentworld.com/?p=61460 expresses the sadness of the various clubs in which Istvan played along his exceptional career. You may read Brian Schembri’s post on behalf of San Giljan ASC amongst the comments on the same page.
The no. 8 San Giljan white cap seen in the photo attached to this post is the one Udvardi wore for the 1994 league decider against Sirens.
Once again RIP Istvan.
