When Sunderland host Stoke City on Saturday, it will see the Championship's two youngest sides face each other.
Both teams have put out a starting XI with an average age of 22.7 this season, the lowest in the division.
Forwards Tom Cannon and Bae Junho and midfielder Andrew Moran are all 21 and have been key players for the Potters, while 20-year-old Junior Tchamadeu has held down an import role at right-back, and 19-year-old Lewis Koumas brings an additional attacking dimension to the side.
"I think that we will see a lot of energy from both sides, because this is what young players give," said Potters manager Marti Pelach told BBC Radio Stoke.
