Rio Ferdinand may be a Manchester United legend and, therefore, a Red Devils fan for life but his children seem a little more open-minded when it comes to their footballing allegiance.
The father of three revealed that he and his two sons, Lorenz and Tate, were present inside the Emirates Stadium when Arsenal demolished Ferdinand's former team 3-0.
All of the goals came during the first 19 minutes of the match and two were provided by the in-form Alexis Sanchez.

The Chilean opened the scoring with an audacious backheel from Mesut Ozil's driven cross before the German himself bagged the second soon after. Sanchez put the tie to bed with a sensational 25-yard howitzer that left a lasting impression on both the goal net and Ferdinand's children.
While the traveling Manchester United faithful pined for the days when Ferdinand and Nemanja Vidic stood tall in defence, the 36-year-old's offspring were busy putting in a transfer request.
He told BreatheSport: "My boys came to the game in Manchester United tops, but they left asking for Alexis Sanchez shirts."
A true star
Sanchez has only gone from strength-to-strength since that pivotal Premier League tie, scoring three goals in two World Cup qualifiers for Chile before once again firing in Arsenal's 3-0 win over Watford.
The 26-year-old now has ten goals in his last six games for club and country and is an early favourite to win the PFA Player of the Year award. He is sure to seal Arsenal plenty more young fans if he can fire them to some major silverware this season.
Louis van Gaal may not have an impact player to compete with Sanchez, but his team put in a rather impressive team performance to beat Everton 3-0 this weekend. Ander Herrera's industrial display from midfield was singled out for particular praise, but it certainly didn't have the razzamatazz of Arsenal's flying forward.
