Greek keeper Dimi Konstantopoulos has featured twice for Boro in cup competition this season and, having celebrated his 40th birthday at the end of November, would become our oldest-ever player should he add another appearance tomorrow.

Boro have never fielded a player in his 40s, with the record currently held by player-manager Bryan Robson on New Year's Day 1997 when he started and played against Arsenal at Highbury ten days short of his fortieth birthday.

Dimi could be joined in the starting XI by our youngest-ever player, 16-year-old Nathan Wood, who set his own record earlier this season at the age of 16 years and 75 days when playing against Notts County.

Tony Pulis revealed in his weekly media conference that the duo will be included in the matchday squad for Peterborough, but remained tight-lipped over who will make his starting XI.

“I think tomorrow we’ll have the youngest player in the club’s history in the squad and the oldest, in Woody and Dimi," he said.

“Having the two of them together, it’s quite a unique situation. 

"It’s unbelievable, really.”

The pair have already shared a pitch when playing against Preston North End in the Carabao Cup earlier this season. The age difference between the pair is 23 years, six months and two days.
