Manchester City could be without Kevin De Bruyne for the rest of the year after manager Pep Guardiola said on Tuesday he may require surgery on a hamstring injury. De Bruyne limped off early in City`s 3-0 win over Burnley to open the Premier League season on Friday. 

The 32-year-old had suffered a similar injury in the Champions League final just over two months ago as City beat Inter Milan to become European champions for the first time. "It`s a serious injury," said Guardiola ahead of the UEFA Super Cup between City and Sevilla in Athens. "We have to decide surgery or not surgery."
