Manchester City are waiting to see if they will be without a fit specialist left-back after Aleksandar Kolarov limped off in Serbia's defeat to Portugal on Sunday.
The former Lazio player, who was subsequently sent off from the bench for showing dissent, reportedly suffered a hamstring problem.
The Premier League leaders will already be without Gael Clichy, who is yet to play this season after undergoing ankle surgery, when they host Bournemouth on Saturday.
Kolarov has been an ever-present in the current campaign but could be sidelined as City face a demanding spell of games, including the Manchester derby at Old Trafford and a Champions League double header with Sevilla.
Both of City's right-backs, Pablo Zabaleta and Bacary Sagna, have stood in on the opposite flank at stages in their careers and one would be the likeliest to step in if Kolarov and Clichy are out at the same time.
Fabian Delph, as a left-footed central midfielder, might be another option but the England international has been sidelined by his second hamstring injury of his brief City career.
Highly rated teenaged left-back Angelino is unavailable after being loaned to New York City FC.
City have already suffered two major injury blows in the international break with Sergio Aguero out for a month with a hamstring problem and David Silva reportedly out for three weeks after hurting his ankle.
