With folded arms and no hint of a celebration, Claudio Ranieri did not even flinch when Fulham took the lead against the team he turned into champions of England.
Facing his old club for the first time since that 5,000-1 triumph in 2016, Ranieri did not want to show disrespect. Perhaps he also knew this game was far from over.
Fulham had not kept a clean sheet all season and now, if they could secure their first, they would climb out of the Premier League's relegation zone. Unfortunately for Ranieri, it was not to be.

It was James Maddison, one of the top-flight's revelations this season, who equalised in the 74th minute to ruin this Leicester reunion for their former manager.
Fulham remain bottom and Ranieri reflected afterwards: 'It was a very emotional match for me. The Leicester fans and Fulham fans sang my name at the beginning and end of the match.
'I think a draw is right. A draw is OK. One point is better than nothing.'
Some Leicester supporters braved the weather and showed their gratitude by wearing T-shirts depicting their former boss as Don Corleone from film The Godfather.
Yet when Ranieri walked out, he kept his head down, appearing determined to avoid all distractions. Fulham had a job to do if they were to avoid becoming history makers of their own.
Not since 1950 had the Cottagers failed to keep a clean sheet in 19 consecutive top-flight games. Maddison's late leveller made sure the wait will go on.
'It was a good goal,' Puel said. 'We found a fighting spirit and a desire to come back into the game.'
Fulham almost conceded within three minutes when Kelechi Iheanacho, starting instead of the injured Jamie Vardy, broke through and had only Sergio Rico to beat.
Rico refused to go to ground and denied Leicester their opener.
Fulham then thought they had the lead when Calum Chambers telegraphed a half-volley towards the far corner. Only a split-second reaction from Kasper Schmeichel kept it 0-0.
It was end to end. Wes Morgan, one of five Leicester players in Puel's line-up who won the title two years ago, sent a free header wide and saw another saved by Rico.
Then it was Fulham's turn again and, this time, Schmeichel was beaten. Mitrovic flicked the ball through for Aboubakar Kamara, whose first touch made the crowd think the chance was wasted.
Yet the French forward produced a clever turn, sending a sliding Caglar Soyuncu off the pitch in the process, and fired the ball beneath Schmeichel for 1-0.
The question now was, could Fulham keep their first clean sheet of the season? Ranieri knows a thing or two about miracles and, well, the statistics said that would be up there.
The Cottagers had conceded at least two goals in 12 of their 14 league games but, instead of sitting back, they took the game to Leicester in the second half.
Puel introduced Shinji Okazaki as a final roll of the dice and the substitute made his presence count immediately. Two minutes after coming on, he crossed towards the back of the box and found an unmarked Maddison, who made no mistake.
With that, the reunion was over, and Ranieri walked off to the soundtrack of his name being belted out by both sets of supporters.
