There will be some who interpret that as the start of some jibe against a goalkeeper who has long since been branded with the nickname 'Clangers' but it was instead one of the throng in front of the Aberdeen man who made the blunder. The calculations were being made as to how many clean sheets Langfield has and how soon he will reach 100 in the Scottish top flight, with his tally having reached 88 ahead of the visit of Inverness Caledonian Thistle this afternoon.
The Aberdeen goalkeeper is now just seven shut-outs behind the record held by Allan McGregor, the former Rangers player, although Langfield was not clutching for credit just yet. With the league now under the auspices of the Scottish Professional Football League - rather than the Scottish Premier League - he was given to wonder whether or not that summer rebranding has caused his previous clean sheets to be folded up and stowed away in the past. That would leave him with two this season and back on square one.
There is a more certain threat to his record coming in the form of Inverness, though, the Highland side currently leading the Premiership. Langfield is not surprised to see today's opponents in such a lofty position but, having experienced too many low points during eight years at Pittodrie, the goalkeeper feels his own side have also shown themselves capable of challenging for the top places in the league. He does not consider a return to European competition to be outwith his reach.
"We were playing against Bayern Munich, Atletico Madrid and FC Copenhagen, who are all involved in the Champions League this season and obviously it's an ambition to compete against sides of that quality again," said Langfield, whose side have doubts over the fitness of both Niall McGinn and Barry Robson. "To do that, we need to finish high in the league but no one in the dressing room is getting ahead of themselves. When you look at the squad the manager has built, and beating Partick Thistle last week with so many players missing, it bodes well for the future.
"As for Inverness, it is no surprise to me that they are top of the league because Terry Butcher and Maurice Malpas [the Inverness manager and assistant, respectively] are so well organised. Their players give everything for them. They have re-jigged their squad again and still got results. [This match] will be a yardstick for the season."
The ripples which have emanated from the big splash Inverness have made this season have yet to be truly felt in the Highlands, though. That is perhaps just as well, since Dean Brill, Inverness goalkeeper, believes that it is the "secluded" nature of the club's heartland which has helped them to keep their balance at the top of the league.
The 27-year-old was recruited on loan from Luton Town in the summer - with Inverness negotiating to have his stay in the Highlands extended beyond January - and he has come to regard their environment as integral to the spirit within the squad. "We are secluded up here, we are quite far away from friends and family," said Brill. "So I can just concentrate on my football and I think a lot of the boys are like that. Because we mingle with each other as well, I think that probably helps us concentrate on football. We are constantly around each other and learning about each other.
"I didn't know much about what the football was going to be like. I remember saying to friends and family I was looking forward to seeing how it would pan out and fortunately it has been fantastic."
