Owen limped out of Saturday's defeat to Arsenal and is now a major doubt for next weekend's Euro 2004 qualifier between England and Turkey.

"The prospect of perhaps losing Owen will be a big blow to England coach Sven-Goran Eriksson as he prepares for the Euro 2004 showdown in Istanbul," sums up the Sunday Times.

"Sven-Goran Eriksson and the nation's football fans will be holding their breath and hoping for good news when Owen goes to hospital for a scan," is the assessment of the Mail on Sunday.

But Owen is not England's only fitness concern, the Independent on Sunday reports that Sven-Goran Eriksson was supposed to be at Anfield on Saturday but missed the game because of a virus.

Off the pitch, the Daily Star says that England will be heavily protected by a huge security operation when they fly to Turkey.

"Seventy cops - including 30 armed Turkish officers will provide a round the clock guard from the moment England touch down in Istanbul," it says.

Despite a 2-0 victory over Blackburn on Saturday and a vote of approval earlier in the week, the Sunday People says that Peter Reid is on the brink of quitting Leeds.

The paper says that "Reid is understood to be seriously unhappy with how he has been treated by the Elland Road board in the last few days."

Elsewhere, the remarkable Paula Radcliffe's victory in the World Half-Marathon Championship in Portugal is widely celebrated although the Bedford runner missed out on another world record.

"Radcliffe's astonishing road-racing season continued but it is a measure of her dominance on the tarmac that her triumph brought a sense of anti-climax," says the Sunday Telegraph.

"But if this race proved she is human after all, it was nevertheless an awesome display."

The Observer reports that the tennis career of Anna Kournikova could be at an end because of a chronic back complaint.

According to her agent Phil di Picciotto, the 22-year-old's career is in such a state of limbo at the moment that she is no longer working with a coach.
