Sir Alex Ferguson retired from management in 2013, but it has now been revealed why the former Manchester United manager is not Pep Guardiola's biggest fan.
Guardiola's agent revealed that Ferguson wanted the player at Man United, but he refused to meet the Scottish manager.
The Manchester City manager was in his final playing year at Barcelona in 2001 when Ferguson contacted the player's agent, Josep Maria Orobitg.
“The first club that went in hard for Guardiola was United. They really wanted him. Pep never wanted to talk about it," Orobitg told the Sun.
“He kept his word, even when it involved Manchester United, a club that any player would have killed to negotiate with.
“United pressed me but I couldn’t do anything. Pep hadn’t yet explained to the Barcelona president he wasn’t going to stay.
“United then gave us an ultimatum, they wanted a face-to-face meeting between Ferguson and Guardiola.
“They had to plan their team and couldn’t wait any longer.
