Real back on top after crucial win at Osasuna

By Richard Martin BARCELONA (Reuters) - Real Madrid returned to the top of La Liga after winning a testing away clash against Osasuna 3-1 on Saturday thanks to goals from talisman Cristiano Ronaldo, midfielder Isco and substitute Lucas Vazquez. Osasuna striker Sergio Leon cancelled out Ronaldo's 24th-minute opener in the 33rd after defender Tano had been carried off with a sickening double leg break.
