Pep Guardiola believes Manchester City will be without Raheem Sterling for "weeks" and cannot be sure whether the forward will be fit for their upcoming Champions League trip to face Real Madrid.
England international Sterling suffered a hamstring injury in Sunday's Premier League defeat at Tottenham and will miss this weekend's home match against West Ham .
City have not specified the severity of the damage Sterling has sustained, and Guardiola did not offer any guarantee that the 25-year-old will be ready to return to action before the end of February.
