Manchester City boss Pep Guardiola says Phil Foden missed victory over Wolves due to injury.
Guardiola revealed Foden had picked up a problem in the derby defeat at Manchester United but that he would be closely monitored this week ahead of Friday's FA Cup fourth round tie at home to Arsenal.
"He was in action, in Old Trafford, jump. With Wan Bissaka. He had a problem with his feet," the City boss said.
"He's struggling so far. (It's) Painful. Two or three days rest. We decide with the doctors to stay and recover well.
"We will see if he arrives against Arsenal. If he's not fit, we will wait until the next game against Spurs. Because otherwise he cannot train well.
"He's a little bit uncomfortable. That's why we decided with the doctors, all together, to two or three days stay off and then see if getting better."
