The Hearts manager does not want to get his hopes up and then risk deflation if Naismith, who underwent surgery on a cartilage last month, does not recover in time.
But Levein admits Hearts reaching the final thanks to Saturday’s 3-0 win over Inverness Caledonian Thistle gives the influential striker “something to aim for”.
The 32-year-old last played in February when he was replaced at half-time against Celtic – who Hearts face at Hampden Park on 25 May. There are five league games before then and it is likely Naismith, who has scored 14 goals this season despite missing two chunks of the campaign due to injury, would need to play in at least one of them to be considered for the final.
“I could say he has a chance …The way I look at it is, if he’s fit, it will be a huge bonus for us,” said Levein. So I don’t want to put all my eggs in one basket by saying he’s going to be fit. I’d rather expect him not to be fit.
“Him being fit won’t be a disappointment. If I put the onus on him being fit and he isn’t, that would be a big disappointment. It’s about wanting to keep my head clear for all the games coming up, not constantly thinking: ‘I hope Naisy’s back next week, I hope he’s back next week, next week …’ He’ll be doing his best to make the final, for sure.”
Saturday’s semi-final victory over Inverness proved Hearts can prevail without Naismith but he has proved central to their hopes often this season.
“I’ve got players who I can rely on, like I rely on Naisy,” said Levein. “Players like Christophe Berra, John Souttar, Arnaud Djoum, Peter Haring and Michael Smith. Naisy was probably more important because he was at the front end of the team. Without him there, we’ve got Steven MacLean, who is obviously 36, nearly 37.”
“We don’t have that person in the front line who keeps everybody calm and makes good decisions,” he added. “So I’m then relying on Uche (Ikpeazu), who is a real handful. But, again, he doesn’t have that experience or knowledge that Steven Naismith has.
“Or there’s Jake Mulraney, a fantastic player who was great against Inverness. He doesn’t have that knowledge, experience and calmness that Steven brings to the team. So we miss him for his football and because of the other things he brings to the team.”
