Nathaniel Clyne was pictured leaving a Liverpool hospital after undergoing a medical on Monday ahead of sealing a move from Southampton. The right back is set to secure a £12.5million transfer – £10.5m up front with a further £2m based on add-ons – to become Brendan Rodgers’s sixth signing already since the season ended. Liverpool have been searching for a right-back after allowing Glen Johnson to leave at the end of his contract and Jon Flanagan out long-term with a knee injury. Provided the medical is passed, as expected, Clyne will follow Roberto Firmino, James Milner, Adam Bogdan, Danny Ings and Joe Gomez to Merseyside.Nathaniel Clyne will become Liverpool's sixth signing of the summerSouthampton defender indicated he would be keen to move to AnfieldReds have agreed a deal which could rise to £12.5m for the England manBrendan Rodgers moved for Clyne after allowing Glen Johnson to leave

Archaeologists say they have unearthed the oldest human footprints ever found in North America. The impressions were discovered buried at a shoreline at an archaeological dig site on Calvert Island, British Columbia in Canada. Charcoal in the prints has been radiocarbon dated, giving them an age of 13,200 years old. The finding was made by the Hakai Institute and the University of Victoria, both in British Columbia. Archaeologists Dr Daryl Fedje and Dr Duncan McLaren excavated an area below the high tide line, and found dozens of human footprints that had remained intact in clay. An ancient skeleton found nearly 20 years ago in a river in Washington is related to Native Americans, says a DNA study that could help resolve a long-running dispute over its ancestry.Human footprints were found preserved on Calvert Island in CanadaThey were radiocarbon dated to a remarkable 13,200 years oldIf confirmed they would be the oldest human footprints in North AmericaDiscovery also suggests people once migrated down the coast
