Wayne Rooney's oldest son, Kai, signs for Manchester United

Wayne Rooney's son Kai has followed in his father's footsteps by signing for Manchester United.

United's record goalscorer posted a picture on social media of the 11-year-old, the oldest of Rooney's four sons, signing a contract at his dad's former club.

Rooney accompanied the image with the caption: 'Proud day. Kai signing for @manchesterunited. Keep up the hard work son.'

Rooney, 38 years of age and now in interim charge of Derby, joined United from Everton in 2004.

The former England striker had a glittering 13-year career at Old Trafford, scoring 253 times in 559 appearances and breaking Sir Bobby Charlton's long-standing goal record in January 2017.

Coleen Rooney wrote on Instagram: 'Special night..... congratulations Kai. I love you and I am so proud of you. Keep trying your best'
