Ash Taylor
It goes without saying that Kilmarnock have to be robust at the back to have any chance of defeating Celtic and making it to the final. Taylor is the leader of the defence and typically starts at the centre of a three-man unit. The former Aberdeen man is one of the most aerially-dominant players in the league, though he'll have to keep his wits about him when the ball is on the deck as Celtic's movement up front can tear apart any side in the country in an instant. He's also a threat from set-pieces (having scored four times already this term) and will be looking to get one in at the right end after scoring an unfortunate own goal in Killie's 2-0 defeat at Parkhead last weekend.
Alan Power
Going up against Callum McGregor, Reo Hatate and co almost feels like a hiding to nothing, but the reigning Scottish champions are not unbeatable and if Kilmarnock are going to cause an upset they'll need to hold their own in the engine room. Power returned to Rugby Park this summer after a spell at St Mirren - he will be 35 later this month but has been impressive this campaign. The Irishman is a tenacious battler but also someone capable of showing a bit of poise on the ball to ensure his side keep possession.
Daniel Armstrong
The former Raith Rovers man has been Kilmarnock's most creative outlet this campaign and is their leading goalscorer with seven in all competitions. He was omitted from the starting XI for the recent trip to Celtic Park but it's hard to imagine Killie getting the desired result without him having a say in matters. The 25-year-old typically starts on the wing but is given freedom to drift inside where he can pick up pockets of space, allowing him to thread through balls or even have a pop at goal himself. If he can produce a bit of magic then his team will have a fighting chance.
