Reigning English Premier League champions Manchester City will be without Kevin De Bruyne with the midfielder facing a spell on the sidelines after injuring his right knee in training on Wednesday.
A club statement said the full extent of the injury is not yet known, but the Belgium international was undergoing tests.
De Bruyne is expected to fly to Barcelona for further tests with Dr. Ramon Cugat, a specialist who treated him when he suffered a knee injury in January 2016.

The 27 year old, who had the most assists in the Premier League last season, had just returned to training on August 6 after helping Belgium to a third place finish at the FIFA World Cup in Russia.
His loss will be a major blow to Pep Guardiola however City will turn to the likes of David Silva, Bernardo Silva and Ilkay Gundogan in his absence.
