Liverpool's Craig Bellamy and Marvin Sordell of Bolton Wanderers started up front, With Arsenal's Aaron Ramsey, Tottenham Hotspur's Danny Rose and Jack Cork of Southampton were in midfield. The back line included Micah Richards of Manchester City, Chelsea's Ryan Bertrand and Craig Dawson of West Bromwich Albion. Jack Butland of Birmingham City started in goal. Team GB have a final friendly with Brazil on Friday in Middlesbrough. Meanwhile, Senegal impressed with a 2-0 victory over Spain's Olympic team, with Ibrahima Seck, a standby player, scoring in the 14th minute past David de Gea, the Manchester United goalkeeper, and Sadio Mane of Metz adding a second in the 47th minute, in Las Palmas, Spain.
