The hope was that some much-needed time away from the game before, during and after the 2022 World Cup, would allow Sancho to decompress and start afresh. Two goals in his first three games after his return hinted at a return to form and there was genuine optimism surrounding Sancho going into the current campaign. But then came his exclusion from the squad to face Arsenal on September 3 and the subsequent spat that effectively spelt the end of his United career.
Everyone has their opinion on who is to blame, including a whole host of former United players. Louis Saha initially suggested Ten Hag was at fault before later slating Sancho for allegedly refusing to play; Dimitar Berbatov argued that Sancho had "overestimated his value" to the club; Dwight Yorke rather amusingly accused Sancho of "strolling through life"; while Roy Keane, of all people, suggested that a simple apology was all that was required to resolve this particular player-manager spat.
However, neither man was willing to back down. Both felt disrespected, making a parting of the ways both inevitable and sensible. Consequently, it now longer matters where the fault lies. All that matters is what happens next, with United and Sancho now on the same page, in the sense that they both need him to make a success of his return to Dortmund.
United desperately need to recoup some of the money they wasted on Sancho, while the man himself simply has to take this opportunity to turn his career around. He may be only 23, but he wouldn't be the first footballer to fall from grace as rapidly as he rose to prominence.
It's certainly hard to see another top club taking a chance on Sancho if he fails to make the most of his second chance at Signal Iduna Park. He used to love playing in front of the 'Yellow Wall'. "It's a crazy feeling," he once said. "Every time I step out on this pitch, I get a nice buzz. I'm just delighted that I'm here and getting an opportunity to play."
He'll be just as delighted to be back. The fans are eagerly awaiting his return, too, while Edin Terzic's team could do with a lift right now. But, as ever, everything depends on Sancho's frame of mind. This feels like the right move at the right time. It's just that now more than ever before there is a serious question mark over whether he'll actually turn up.
