Aaron Ramsey and Jack Wilshere made their Premier League debuts two minutes apart in 2008; a 17 and 16-year-old coming on as substitutes for Arsenal in a 4-0 win at Blackburn Rovers.
On Saturday, the two men will be reunited in opposing dugouts as fledgling coaches.
Wales captain Ramsey will be taking charge of Cardiff City for the third – and, for now, seemingly final – time when the already-relegated Bluebirds visit Norwich City in the Championship.
The 34-year-old is still registered as a Bluebirds player but was handed the reins on a temporary basis after Omer Riza was sacked last month.
