The answer is Josh Sheehan and Rod Wallace: What is the question?

Wanderers fans with a good memory might just recall that they are the only men since the turn of the millennium to score a winning goal for the Whites in a penalty shoot-out.

It is the uncomfortable reality that neither set of fans want to consider ahead of Friday night’s second-leg tie at Oakwell, that a whole season’s work could boil down to the relative lottery of spot kicks.

Bolton have done their homework. Typically, Ian Evatt, Chris Markham and their analysts have scrutinised every detail of Barnsley’s previous history in the hope of making James Trafford better prepared.

In Markham, Wanderers have someone whose work once helped Gareth Southgate’s England team turn around their woeful penalty shoot-out record at the 2018 World Cup.

Bolton have won four of their 12 shoot-outs in competitive games, stretching back to their very first against Chester City in the 1983/84 League Cup.

Happily, their most recent win was only last season, and against Barnsley to boot.

On that occasion, a Carabao Cup first round tie, Devante Cole had his penalty saved by Joel Dixon to leave Sheehan the responsibility of slotting in the winning kick.

“I think Joel (Dixon) had saved the one before and then I scored,” the Welshman recalled. “I remember it went top left to put us through.

“Every penalty shoot-out, it just depends how players feel on the day. I think most of the players on our team would put their hand up and go forward if it went to penalties on Friday.

“I’ve always been confident to take them and I’ve had a few in my time here. I’d definitely put my hand up again.”

A small scattering of supporters might have watched Owen Coyle’s Bolton team beat Toronto FC 4-3 in a shoot-out to lift the Carlsberg Cup at the end of a friendly tour of North America in 2010 but their previous competitive penalty success had been 20 years earlier when Sam Allardyce’s side knocked out Southampton at the Reebok by virtue of Chris Marsden’s miss, and Rod Wallace’s deciding kick.

To add some balance, Bolton have lost also their last two – at Tranmere and Wigan – where Lloyd Isgrove and Nathan Delfouneso were the unlucky souls on the night.

Evatt and his coaching staff have done what they can to prepare the players, or at least make them more comfortable should the need for penalties arrive.

Sheehan was in the Newport County team that beat Mansfield Town on penalties in the 2019 League Two play-off semi-final, and admits while practice may help to a point, the pressure of the situation means you still have to think on your feet.

“You practice the technique and making sure where you are going to go and how hard you are going to hit it,” he said. “But it is completely different when you step up in front of the crowd.

“Even the keeper’s movement or where he is standing in the goal can change your mind, which it has with some of the ones I have taken. He might be stood too far to the left and I have changed where I put it.

“Everything can change but when you step up to actually hit it, you have just got to be confident with your strike.”

Wanderers have beaten Barnsley on their own patch once this season, and Sheehan expects the result to get a mention over the next 24 hours as Evatt prepares his team for the biggest game of their season to date.

“Those things will be said towards the end of the week,” he said. “Building up towards that game, we know what we can do.

“We have done it there – on that ground, in that space and on that pitch. Everyone is going to be looking forward to it.

“We all have to do our jobs and make sure we stick to it. Everyone will be giving it their all, there is going to be nothing left out there.”

Sheehan says the frustration of Saturday has now died down, giving way to a determination to join Sheffield Wednesday in the final after their stunning comeback against Peterborough United last night.

“We are always positive," he added. "We were positive going into the last game, we just didn’t perform how we wanted to. But that is behind us, it is a one-off game now.

"No-one is leading, no-one has a different mentality. Both teams go into it wanting to win a one-off game because we know what is at the end of it.”
