Captain Vincent Kompany will miss Manchester City's crunch Premier League clash against Arsenal but the full extent of his latest injury is not yet known.
Kompany was substituted during the early stages of Wednesday's 1-0 Champions League semi-final defeat to Real Madrid having suffered the fifth injury of a heavily disrupted season.
The 30-year-old's problem on this occasion appeared to be a groin strain as opposed to a recurrence of the calf injuries that have dogged his progress and called into question whether he can continue to hold a prominent role in the City squad under Manuel Pellegrini's successor Pep Guardiola next season.
"We don’t have the medical examination on Vincent - he's with the doctor," Pellegrini told a pre-match news conference. "On Monday we will know.
"For Vincent it’s an issue for the future - we must talk with the doctor, with the player, with the people who will be in charge of City next year. It's a medical issue.
"Every time he was in the XI he was fit to play, 100 per cent. You can be sure of that."
City's prospects of being a Champions League club when Guardiola arrives from Bayern Munich are likely to hinge on Sunday's result, as they sit three points behind third-place Arsenal and four ahead of Manchester United, who have a game in hand in fifth.
"It's a special game because we finish here at home after three intensive years," Pellegrini said. "We've always received support of the fans, so we're really happy with them.
"For me, the second season was the worst - if we can finish in third in this third season it wouldn't be extraordinary but still a good season.
"I will have emotions on Sunday but I prefer not to show them in an external way. As a manager you must try to dominate your emotions. If not the probability of a bad decision is quite high."
