Jack Fletcher is still ahead of father Darren in his development at Manchester United despite Youth Cup agony

"When they're on the pitch, we don't know which is which" was a chant incepted for the Da Silva twins and it could soon be allocated to the Fletchers.

Tyler and Jack were regulars in the Old Trafford directors' box last season while still in the Manchester City academy and in attendance on derby day. Amid the bedlam over Bruno Fernandes' equaliser and Marcus Rashford's winner, nobody clocked whether the teenagers dared to celebrate.

The 16-year-olds' allegiance will almost certainly have been with their father, Darren. The United technical director has to walk past the front row of journalists in the press box to take his seat with the United analysts towards the back of the Sir Bobby Charlton Stand. Occasionally, he will wave at his sons and wife Hayley.

The Fletcher twins' devotion to the red side of Manchester was confirmed when they crossed the divide to join United's academy in the summer for a combined fee of £1.25million. Should they emulate their father, they would become the 13th set of brothers to play for the United first team.

Jack and Tyler were born on the same day Cristiano Ronaldo settled an FA Cup quarter-final replay with Middlesbrough in March 2007. Darren was present for their birth as he was recovering from an ankle injury.

It was barely seven years ago that nine-year-old Jack and Tyler Fletcher were having a kickabout on the Hawthorns pitch with Kai Rooney eight days before Christmas. Darren was halfway through his final season at West Brom and soon started heading up the M6 and towards home in Manchester, spending two years with Stoke City.
