Whether the stories about a faulty fax machine scuppering David de Gea's move to Real Madrid are true or not, Manchester United must count their lucky stars nonetheless.
It is now three years since the Madrid-born goalkeeper was on the verge of heading home, only for the £22million deadline day deal not to go through in time.
Real accused the Premier League club of filing the paperwork late, while United acted innocent. Whoever was to blame, Jose Mourinho is benefitting from it now.
Ask any defender and he will tell you about the sense of security felt when you see someone so sturdy behind. They are their safety net, should things get hairy.
That is what United centre backs Chris Smalling and Victor Lindelof had on Saturday. De Gea will have busier days than this, of course, though his contribution at Vicarage Road was still significant.
Were it not for him, Watford would have been 1-0 up within the first 20 minutes. Were it not for him, United would have conceded a leveller deep into stoppage time.
The home side, after four successive Premier League wins, had their tails up at the start.
Javi Gracia's players were the ones pushing for the opener while United politely sat back, inviting their opponents to give it a go. De Gea had to stay alert.
The closest they came to scoring was when a long ball was aimed towards Troy Deeney. Watford's big lump chested it down and moments later had his chance to shoot.
Deeney struck a sweet shot which was rising into the back of the United net until De Gea got a hand to it. Replays showed it was one we would now expect of the best goalkeeper in the English game, but he made no mistake.
Had that gone in, the way Mourinho's United were playing at the time, they would have had a mountain to climb. A goal down, heads would have dropped.
Instead, they went on to take a 2-0 lead before half time. Watford scored in the second half through Andre Gray, though it was through no fault of De Gea's. He was left helpless.
In stoppage time, with United down to 10 men, Christian Kabasele headed for goal from six yards. It was flying in, fans were about to rise to their feet in celebration, then De Gea intervened.
The Spaniard flew himself to his left, denying Kabasele his dream goal. Once again, United's fans were left thanking the heavens that fax never went through in 2015.
