Ralf Rangnick remains unbeaten as Manchester United's interim manager, with two Premier League victories and a draw in the Champions League against Young Boys rounding off a decent start to life in the Old Trafford dugout.
United haven't exactly been blowing teams away since Rangnick was appointed, though their record of one goal conceded in three games is a marked improvement when compared to the side's results at the back end of Ole Gunnar Solskjaer's reign.
While some fans have been quick to note the so-called 'easier' fixtures Rangnick has been tasked with navigating since being appointed, the hectic Christmas schedule must be approached with caution.
'Rotation' will be the buzzword for the next few months and with a talented squad available to him, it should leave the German with plenty of options as the games come thick and fast.
However, if Rangnick gets his squad rotation wrong then he could fall into the same trap that Solskjaer did during his time as United manager and his honeymoon period could soon come to an abrupt end.
Solskjaer's issue was he didn't rotate his squad enough. He relied too heavily on star men like Bruno Fernandes, Marcus Rashford and Harry Maguire, and towards the end of last season, the aforementioned players were clearly in need of a rest. However, Solskjaer couldn't risk rotating his key players as United approached the business end of the season.
Rangnick is unlikely to be afforded a dead rubber game like the one against Young Boys again this season, therefore he will have to manage his squad accordingly.
Rangnick will also have to remember that just because he can rotate his squad, it doesn't mean he has to. Saturday's hard-fought win against Norwich proved that while United are trying to adapt to the German's system, results won't come easy.
Until the United boss' philosophy is fully implemented, United may need to rely on their star players to carry them through, meaning that Cristiano Ronaldo, Jadon Sancho, Fernandes, Fred and a host of the club's other key players may need to continue starting until Rangnick's style of play almost becomes second nature to them.
There's a fine line between selecting the same starting XI in the hope they can adapt to a new system and overplaying your key players so much so that they're too tired as the season reaches the home straight. It's up to Rangnick to strike the right balance and avoid falling into the same trap as Solskjaer.
