- Walker injured in Manchester derby
- Sat out City's dominant UCL victory
- A doubt for World Cup in Qatar
WHAT HAPPENED? Walker missed out as Manchester City thrashed Copenhagen 5-0 in the Champions League after picking up an injury in their 6-3 derby win over Manchester United at the weekend. City have released an official statement confirming that he has undergone successful surgery on the groin issue, but he is now facing a race against time to be for the World Cup.
WHAT THEY SAID: "It's something abdominal and he will be a while out," Guardiola admitted to reporters after his side's latest European win: "I don't know [how long]. I cannot say anything else. We have to speak to the doctors. Hopefully he can get back like Kalvin [Phillips].
"I know how important the World Cup is for the players but honestly I don't know right now."
THE BIGGER PICTURE: Walker could now be a major doubt for the Qatar tournament. It was widely anticipated that he would be called up as a key part of Gareth Southgate's plans, with the 32-year-old having won 70 caps for England to date.
