Police investigate alleged racial abuse
NEWCASTLE, England (AP)
Kolarov, who is Serbian, was warming up as a substitute when he is believed to have become involved in a lengthy exchange with a fan who was carrying an Albanian flag.
Northumbria Police say they have ''received a report of racist language having been used at the St James' Park stadium,'' adding that ''enquiries are ongoing into the incident.''
There is a long history of tension between Serbia and Albania, particularly over the disputed region of Kosovo.
Kolarov came on as a 37th-minute substitute in City's 3-1 win.
