O'Neill outlines defensive worries

Northern Ireland manager Michael O'Neill outlines his defensive worries for the World Cup qualifier with Portugal and says he will have to "improvise" if key players are not passed fit.

Craig Cathcart has been ruled out, Daniel Lafferty is suspended and Aaron Hughes and Ryan McGivern are both rated doubtful because of injury.

O'Neill says the atmosphere in the NI camp is "positive" and adds that he welcomes the chance to work with the players soon after last month's 1-0 win over Russia.
