Vincent Kompany is expected to fly to Germany or Denmark to consult a specialist over a groin injury he picked up on Saturday.
The Manchester City captain has been ruled out of representing Belgium in the upcoming World Cup qualifiers against Croatia and Wales.
Kompany, expected to be out for at least a month, picked up a similar injury in the Blues opening game of the season.
Manuel Pellegrini is understood to want to send the 27-year-old to see a leading specialist in Germany or Denmark.
A source from the club told the Daily Star: “The injuries are piling up and it is looking like only a matter of time before he flies out to consult a specialist.
“His long-term health and fitness have been a big concern for some time now, dating back as far as the end of last season, which was very much an injury-hit campaign for Vincent.
“The feeling now is so that he is at a point where it is difficult to avoid muscle injuries for more than a month or so.”
The source also pointed out how much disruption having their captain missing was causing the Blues.
“This causes untold disruption, not only to the team’s confidence and preparation but also to the player’s body,” the source said.
“When he is playing he is striving for match sharpness. Players need continuity, but these injuries are interrupting his flow.
“He hurt his upper groin and that area in particular is really susceptible for Vincent.
“As you can expect he shares everyone’s frustration.”
