[EX Q]: (CNN) -- The Circuit of the Americas in Austin, Texas lies just 200 miles from the Mexican border. On Sunday it will host the first U.S. Grand Prix since 2007 -- and thousands of Formula One fans are expected to cross the Rio Grande to cheer on a driver they know as "Checo." Sergio Perez has become one of the darlings of Mexico, a country that in recent times has become more synonymous for the drugs war waged by Felipe Calderon during his tenure as president. The sporting focus this weekend will be on America, but the problems of its neighbor will come into sharp focus in the Mexican town of Nuevo Laredo -- the closest crossing point for those hoping to see Perez at what is, in effect, his home race.Formula One driver Sergio Perez looking forward to his "home" race in Texas on SundayThe Mexican is expected to have thousands of fans crossing the border to support himHe has been one of F1's surprise success stories in only his second season on the gridPerez has earned a big-money move to McLaren after three podium placings in 2012

[EX Q]: You could have been forgiven for mixing up which line-up cost £230million. Long-time Premier League title favourites Manchester City were comprehensively undone by the Stoke City pair of Marko Arnautovic and Xherdan Shaqiri, whose combined price tag of £15million was half what Manuel Pellegrini paid for holding midfielder Fernandinho alone. Arnautovic scored twice inside the first 15 minutes, both brilliantly assisted by Shaqiri, as Pellegrini's side drifted badly in the swirling Britannia cross-wind. Without Vincent Kompany, Pablo Zabaleta, Yaya Toure and Sergio Aguero – all injured – the richest club in England looked bereft of leadership. Centre halves Martin Demichelis and Nicolas Otamendi rarely looked like they inhabited the same planet, let alone being team-mates for Argentina.Marko Arnautovic fired Stoke City ahead from close range on seven minutes after Xherdan Shaqiri's crossArnautovic doubled the Potters lead on 15 minutes with a neat finish following from Shaqiri's brilliant through ballStoke's No 10 came inches to scoring a first-half hat-trick before the interval but his strike hit the postVisitors played the final 16 minutes with 10 men after Fernando was forced off with a hamstring injury
