I Don't Know My Starting 11 Yet Insists US Head Coach Bruce Arena"newsNORDERSTEDT Germany (Reuters) - U.S. coach Bruce Arena reported a clean bill of health for all his squad on Tuesday after continuing their World Cup buildup under a veil of secrecy. The Americans played a practice match with fellow finalists Angola behind closed doors on Monday night winning 1-0 after the Africans were reduced to 10 men. On Tuesday following an open training session watched by 1000 Arena was typically cautious about revealing his hand before their opening Group E match against the Czech Republic on June 12. 'I don't know the first 11' he said. Midfielder John O'Brien who was key to the team's run to the 2002 quarter-finals but plagued by injuries since has been progressing nicely after returning from a long layoff in April. 'O'Brien's doing fine' Arena said. Another previous injury worry captain Claudio Reyna who was struggling with a knee problem also played without a setback. 'I don't have any problems any more' Reyna said. 'Everything's running on schedule.' Arena saw nothing strange about playing fellow-finalists with no spectators. 'Angola was just practice' he said after a training session opened to the public. 'Why should it be open? We don't have the public facilities for people to be there. We're playing with 15 players. 'It's a pretty simple game. There will be no secrets in the tournament. We all know each other.' Angola were down to 10 men from late in the first half after defender Loco was sent off for a second yellow card Angola captain Fabrice Akwa said.
