Lubomir Moravcik trusts his "clever" old team-mate Neil Lennon to get his team selection right for Celtic's delayed William Hill Scottish Cup final against Hearts on Sunday.
Young midfielders Ismaila Soro and David Turnbull impressed in the recent wins over Lille and Kilmarnock after being given their chance to help the Hoops arrest their poor run of form.
Veteran skipper Scott Brown, who has led Celtic to the brink of a quadruple domestic treble and nine successive titles, was among the substitutes along with Tom Rogic and, for the Killie game, Ryan Christie.
Whether any or all of them return for Hampden Park is subject to mounting speculation, fuelled in part by Lennon when he hinted he could be loyal to the players who got them to the final against the Championship leaders.
Moravcik played for Celtic between 1998 and 2002 and was in the Hoops midfield with Lennon when the Parkhead side clinched the domestic treble in 2001.
The former Slovakia international said: "Scott has been out of the team for two games but I trust Lenny, he is a clever man, he wants to win the game.
"He will pick a starting XI whom he trusts, and if Scott is ready I am sure he will start and be an important part of the team.
"But it is up to Lenny, he knows why Scott was out and if he is ready physically. If Scott is ready he deserves to play because he is an important man.
"I don't know if the young guys are ready. It is a special game, a final, you have to be psychologically ready. Maybe they have the quality to play again. Why not? It is up to Lenny to trust them."
