Louis van Gaal has quelled talk of a dressing-room mutiny, but it is a fan revolt that he needs to be equally wary of.
Patience is wearing thin with the Dutchman's uninspiring brand of possession football, and if Manchester United supporters don't see a change then the mutterings of discontent could quickly turn into howls of derision.
While wholesale change will not happen overnight, there is a quick-fix available to soothe the disenchantment amongst the Red Devils - a victory over rivals Liverpool.

The visit of the Merseyside outfit is the perfect opportunity to temporarily calm the unrest. Aside from the derby against Manchester City, there is no other game United fans want to win more than the one against their historic rivals.
This evening's game offers LVG the chance to stem the tide and earn back some goodwill from the fans. Of course, it will only be a short-term solution, but it would be a good start.

Van Gaal's task has been made a great deal more difficult by the news that star striker Wayne Rooney is likely to miss the clash of England's fallen giants with a hamstring injury.
However, the very real prospect of David de Gea's return to action should provide the beleaguered boss and his side with a huge boost. The Spaniard's potential return promises to make the atmosphere inside Old Trafford even more special than normal.
Van Gaal, though, has hinted that he still does not know if De Gea will start. Should he not play, and United were to lose, the Dutchman would risk alienating the fans further.
Since his arrival in Manchester 14 months ago Van Gaal has spent an estimated £251 million on 12 players. He has thus far purchased a new player for almost every position on the field. Make no mistake, this is a Louis van Gaal team.
Yet despite the massive spending, he comes into his 51st game in charge with much the same record as his predecessor David Moyes. Should he fail to win today, he will have the same win ratio as Moyes had in his 51 game reign.
During his brief spell in charge Van Gaal has managed to fall out with a number of his star players, most notably Angel Di Maria and Victor Valdes. Fans are growing weary of opening up the back pages to find that their manager has had a row with yet another one of his players.
Marcus Rojo is the latest star to have found himself on the Dutchman's blacklist. With centre-backs currently in short supply it is hardly an ideal situation for the club.
A win against Liverpool at Old Trafford is vital for Van Gaal. With the Champions League opener against PSV Eindhoven to follow on Tuesday, United badly need the morale boost of a victory over the old enemy.
With everything that is at stake it promises to be an interesting game.
