Celtic's battle of the average goalkeepers is far from resolved, even if Martin O'Neill selects one of them coming out of the international break.
"I would like to know what Sam can do, and I think this is the whole point. I know exactly what Sinisalo can do now," said Martin O'Neill when temporarily installing Sam Johnstone as his number one for a run of games going into the break.
He later added: "It'll take us a few weeks before we find out who will stay in goal for hopefully the rest of the season."
It's expected O'Neill will make that decision during this break having seen Johnstone in action for a few weeks now, but who does he go with?
The majority of fans we polled on social media voted for Viljami Sinisalo, but the momentum is obviously with Johnstone, given he has played most recently and Celtic have won their last two games.
But we have to be careful not to get too caught up in the race between the two. Let's be honest, there is no clear winner. They are two closely-matched goalkeepers and both are very average. Neither is making huge mistakes. You could argue that Sinisalo is better with the ball at his feet and wants the ball at his feet more often, but Johnstone is a little more commanding in the air.
Some fans were unimpressed that Sinisalo let in some long-range goals, but this Celtic teams gives up free shots with little pressure from the edge of the box, and at this level, teams are going to produce accurate shots without any pressure.
The reality that Celtic failed to find genuine competition for Sinisalo during the summer when they knew full well they would need to sign a goalkeeper from minute one of the summer transfer window. It was a clear failure.
They instead settled for an ageing loan keeper who is much the same as Sinisalo in terms of talent. When Celtic fans have the debate, it's often made out as if there is a clear winner between the two, depending on what side that fan is on, but we can surely agree that there is very little in it and neither is going to set the world alight.
From long-term perspective, I would argue that Sinisalo is the right choice because he is still only 25 years of age, he is owned by the club and the Bhoys can actually get something from playing him, whether that's a future number one or a decent fee should they sell him.
Playing Johnstone does little, given he is on loan and a veteran keeper who is not going to improve. Unless the former England international is clearly better than Sinisalo, they he should arguably default to number two.
But only under contract until the end of the season, O'Neill is unlikely to think like that, likely to prioritise results over all else, and you can understand that perspective in his situation.
O'Neill tends to lean on more senior players, so it's likely he will trust Johnstone more and make him his number one, but how much difference does it really make?
