Dan Walker previews a busy week of international football, as the qualifying competition for the 2010 World Cup draws to a close.

The Republic of Ireland still have a chance of direct qualification if they beat Italy but are more likely to be battling it out for a place in November's play-offs. Northern Ireland also have a chance of reaching the play-offs - Nigel Worthington's men have a must-win game against the Czech Republic and will be hoping their main rivals Slovenia slip up.
