Cvancara 'ready to go' at Tynecastle with Kenny a doubt

Manager Martin O'Neill hinted that new signing Tomas Cvancara will make his Celtic debut in Sunday's vital Scottish Premiership trip to Heart of Midlothian with fellow striker Johnny Kenny doubtful because of a calf strain.

The 25-year-old Czech Republic international arrived on loan from Borussia Monchengladbach on Thursday, tasked with solving Celtic's centre-forward issues and firing the defending champions back towards the top of the table.

O'Neill's side travel to the capital this weekend trailing leaders Hearts by six points and having lost both matches against the Edinburgh side this season.

Despite the magnitude of the game and Kenny's injury, Celtic's interim boss was keen not to pile too much expectation on his new arrival.

"He trained this morning and he's ready to go," O'Neill said. "I wouldn't want to put too much pressure on him - he's not just going to be the panacea for all our ills and woes.

"Just let him get settled in, I think he'll make an impact, I hope he does.

"But, again, I just wouldn't want to be putting extreme pressure on him to solve all our problems.

"He's making the commitment, he wants to play well, he obviously wants to do well with us and maybe as a consequence he gets himself back into the Czech Republic team."

Kenny picked up his calf issue during Thursday's 2-2 Europa League draw with Bologna, but O'Neill's striking options are bolstered by the return to training of Kelechi Iheanacho, who has not featured since limping off in the Premier Sports Cup final defeat by St Mirren last month.

"It might be a bit of a stretch to start him in a game at the moment, but at least he's going to be available," the Northern Irishman said of the Nigeria international.

Hearts beat Celtic 3-1 at Tynecastle in October - Brendan Rodgers' final match in charge - and triumphed 2-1 at Parkhead in December as Wilfried Nancy began his ill-fated tenure.

O'Neill handed over the reigns to Nancy having won all six of his domestic matches in a ship-steading spell following Rodgers' resignation and he has maintained that perfect record since returning to the club.

However, Hearts have been Scotland's standout team this season and O'Neill knows how consequential the match could be in the title race.

"It's going to be very big, no question about it," he said. "If we get beaten, it's a long way back for us.

"I think it's not the end of the road, but nine points would be a lot to claw back in 15 games left."

O'Neill hailed the work done by Hearts head coach Derek McInnes and expects a "fiery" reception on Sunday.

"Terrific, it's really been brilliant," O'Neill said when asked about Hearts' season to date.

"I was nearly going to say they've taken advantages of Celtic and Rangers slip-ups, but that's not the case. They've driven on themselves and it's genuinely great credit to them."
