It is believed that four men broke into the former Arsenal striker's London home while he was working as a pundit in Brazil last night.
The 50-year-old's manager told The Sun: "It was a terrifying ordeal. They marched Ian's wife from room to room. I would like to thank ITV for helping Ian to get home as quickly as possible."
According to The Mirror, the gang held the knife to wife Nancy's throat while threatening to cut off their children's fingers if she did not give them cash and valuables during the break-in.
