Swedish keeper MagnusHedman tipped Etxeberia's shot round a post with the score still at 0-0 and made a brilliant point-blank save to deny Gaizka Mendieta on 52 minutes.
Kihlstedt is Magnus Hedman's deputy and Antonelius is a reserve defender who is also not expected to start in the Group F opener against England at Saitama on 2 June.
Bradford were so far off the pace that Coventry keeper MagnusHedman had to make just one save in the whole game - and that not until the contest was an hour old - when he kept out a Dean Saunders free-kick.
