A fog engulfing the boisterous FC Porto fans made it difficult for visibility and clarity as Manchester United and Porto's players tip-toed their way onto the pitch for their Europa League tie on Wednesday.
The thick mist, which made visibly virtually impossible for players and the cameras before the teams lined up for the pre-game Europa League anthem, was ominous of another gloomy chapter in United's unending crisis as Ten Hag failed to envisage what lay ahead of his team.
United managed to earn a point despite being reduced to 10 men and leading twice against a dogged Porto side.
The latest catastrophic crumble, giving away a two-goal lead in the space of seven minutes, was preceded by a 3-0 league mauling by Spurs on Sunday.
