Manchester City boss Manuel Pellegrini hopes to have David Silva and Raheem Sterling available against Juventus on Tuesday, but Sergio Aguero is a major doubt for the Champions League opener.
Spanish playmaker Silva was left out of Saturday's last-gasp 1-0 win at Crystal Palace to rest an ankle knock, while England winger Sterling was sidelined by a hamstring strain.
But the key duo are expected to be in the frame when City get their European campaign under way at the Etihad Stadium, with Pellegrini saying: "I hope both of them can be fit on Tuesday. We will see."
However, striker Aguero -- who played down the extent of his injury after Saturday's win -- could miss the Group D curtain raiser after limping off during the first half against Palace with a knee injury.
Thanks everyone for your concern. I got a hard hit and it prevented me from playing more. It doesn't seem to be a serious injury though

Pellegrini was angry that the challenge by Eagles skipper Scott Dann which forced Aguero off was not punished with a red card, and is waiting for an update on the Argentine forward's fitness.
"It was an important kick on his knee," the coach said. "We'll see if he can recover between now and Tuesday. It's very difficult to say now. It's important to see how he recovers. We'll see."
Following Aguero's premature departure it was left to 18-year-old substitute Kelechi Iheanacho to hit City's last-minute winner and maintain their 100 percent record this season.
Victory left City five points clear at the top of the Premier League on Saturday evening, and 11 points ahead of champions Chelsea.
"It's important to have a good start, to have 15 points from five games," added Pellegrini. "We're not just playing against Chelsea, although they are the champions. It's an important gap.
"We were eight points behind last year and, in January, we were level. If you lose points at the beginning, you can lose them in other parts of the year. We have to continue playing the way we are."
