ROME (AP) - Officials in Rome and Naples have promised to have their soccer stadiums ready by May 15, three weeks before World Cup play starts, the head of the cup's organizing committee said Saturday.

''They're still working in Rome and Naples, but we have total, absolute guarantees from CONI (Italian Olympic Games Committee overseeing work at Rome's Olympic Stadium) and the city of Naples that they will be ready.'' Luca Cordero di Montezemolo said.

The World Cup opens June 8 in Milan with a match between defending champion Argentina and Cameroon.

Montezemolo previously had criticized delays in construction, especially at Naples' 80,000-seat San Paolo Stadium, which at first he feared would not be ready in time for the month-long competition.

In mid-April, the Italian minister for urban areas, Carmelo Conte, said that all 12 stadiums hosting World Cup play would be ready by May 31.
