Celtic left-back Greg Taylor expects former mentor Peter Leven to have Aberdeen well drilled for their semi-final meeting.
Leven will again take caretaker charge of the Dons for their Scottish Cup game against Celtic at Hampden on Saturday.
The former Kilmarnock midfielder has had two spells in charge this season, following the departures of Barry Robson and Neil Warnock, and his first game saw Aberdeen draw 1-1 with Celtic at Pittodrie.
Leven is set to stay in charge for the remainder of the season before Elfsborg manager Jimmy Thelin arrives at Pittodrie to take over.
Former Kilmarnock left-back Taylor said: “I think they will be a difficult opponent, that has shown in all the games we have had this year.
“Obviously their league form hasn’t been what they wanted, there are no secrets there, but I think Peter Leven has got them playing some good stuff.
“I worked with Peter at Kilmarnock and I know he is a real top coach, so I’m sure it will be a really difficult game.
“He is a really honest guy, he wants to play football the right way, in my eyes, he wants to play from the back and try and control the ball.
“And he was always very invested in youth. When I was at Kilmarnock coming through, he put a lot of his own time into trying to make me a better player. So he is someone I will always be really grateful to.”
