Manchester United paid a 'premium' for Monaco's Anthony Martial in a bid to beat off competition for the teenager's services from Barcelona, Paris St Germain, Chelsea and Manchester City. A source at the club likened the situation, which saw United shell out a highly-criticised fee for the 19-year-old of £36million, to that of the capture of Cristiano Ronaldo from Sporting Lisbon 12 years ago. The Portugese, then 18, cost United £12.24m in 2003 - a sum which raised eyebrows across the world of football.

Washington (CNN) -- Unmanned aircraft patrolling the nation's borders have an accident rate seven times greater than general aviation aircraft, and hundreds of times greater than the rate of jetliners, federal officials said Thursday in urging caution in expanding the use of pilotless planes. Unmanned aerial vehicles, or UAVs, have proven remarkably useful in the skies over Iraq and Afghanistan, but are difficult to integrate into U.S. skies, the most complex airspace in the world, FAA official Nancy Kalinowski said in testimony before a House Homeland Security subcommittee. Kalinowski said the accident rates for Customs and Border Protection (CBP) aircraft are based on a relatively limited use of the planes -- only 5,688 flight hours. But because of the limited data, "the FAA must make conservative decisions" concerning integrating UAVs into U.S. skies, Kalinowski said.Unmanned aircraft have higher accident rates than regular aircraftThe FAA urges caution in expanding the use of pilotless planes in the United StatesAn FAA official told a House subcommittee that the agency must make conservative decisions on the issue
