Manchester City manager Pep Guardiola is waiting to find out the severity of Kevin De Bruyne's injury suffered in the 1-0 win over Tottenham.
The Belgium midfielder, only recently back from a knee problem, limped off in the first half at the Etihad Stadium as City returned to the top of the Premier League and gained revenge on Spurs following their Champions League exit in midweek.
Phil Foden, on just his second Premier League start, scored the only goal of the game just five minutes in.
The matches keep coming thick and fast for City, who head across Manchester to Old Trafford on Wednesday and Guardiola does not expect De Bruyne to be part of the squad for that game.
"I didn't speak with him or the doctors. It is a muscular injury and I don't know how big the impact is," the Spaniard said.
"We will see tomorrow but I think the next game he will be out.
"I didn't speak (to him). He put his hands in the hamstring position. Tomorrow we will know."

City were unable to build on their perfect start and they allowed Spurs a number of chances, and on another day the Londoners could easily have taken a point.
It was an edgy second half but City ground it out to earn the three points and put the ball back in Liverpool's court ahead of their visit to Cardiff on Sunday.
Guardiola accepted his side were playing "to lose the Premier League" and has hailed their achievement in the league this season.
"It was not our best performance comparing the other day but today they played with nothing to lose and we play to lose the Premier League," he said.
"And after our defeat last Wednesday it was really tough, the last two days, but I like it being tough.
"We started incredibly well. Tottenham is an incredible team but we are there, with 86 points after 100 last season, it is one of the most remarkable things in my career.
"Especially after 100 points, with the best Liverpool ever, one of the best sides I ever played (against) and every three days being there, being there, being there - it is remarkable.
"I want to win it, but I will not judge if not. Tottenham is going to finish top four with the games they have, three at home, so they didn't have the pressure we had, so what we have done is massive."
