Celtic B boss Tommy McIntyre believes former Hoops could cause his team an issue in the Glasgow Cup against Clyde tonight.
The Bully Wee's cup account is opened against a young Celtic side, who won the competition in 2019.
Danny Lennon's Clyde will also take on a Rangers youth team, Queen's Park and Partick Thistle during the tournament.
Former Parkhead youngsters Paul Kennedy and Kieran McGrath - on loan at Berwick Rangers - are now at Clyde, and McIntyre is aware of them.
“They had a good win on Saturday against East Fife (a 3-1 victory), we can’t underestimate Clyde," McIntyre told club media.
"Clyde have a strong pool of players and there’s one or two ex-Celtic players there as well so they’ll want to do well.
“It’s a league table we play in, it’s not just a one-off game.
"We play Queen’s Park, Partick Thistle, Clyde and Rangers. It’s always enjoyable, it’s always something a bit different.”
