Roy Keane has backed Pep Guardiola for after footage emerged of the Man City boss lecturing serial autograph hunters near his home.
The 53-year-old was targeted by would-be autograph hunters, who asked for shirts and other memorabilia to be signed.
Guardiola identified two as wanting to cash in by selling memorabilia bearing his signature and gave a strong response as he pleaded for them to make better choices.
'Don't come again, I won't tell you again, I know your faces,' Guardiola said.
'Go to school and prepare yourself guys. You are young guys so don't be here, wasting time,' Guardiola told the awkwardly-stood trophy hunters clutching replica shirts.
