Ruben Amorim has made six changes in successive games at the start of his Manchester United reign - to rotate amid a hectic fixture schedule as much as to offer all players a taste of his vision. It will likely be the same in tomorrow night's blockbuster Premier League clash against Arsenal.
Lisandro Martinez and Kobbie Mainoo's one-match suspension will enforce two switches off the bat at the Emirates Stadium.
But Amorim is expected to make further alterations in his toughest test as United head coach yet - by a country mile.
The Red Devils soared to a 4-0 victory against Everton at Old Trafford on Sunday to breach the top half of the Premier League table.
Marcus Rashford and Joshua Zirkzee's braces - and Amad's Player of the Match masterclass - made for a jubilant afternoon in M16.
However, it was a more complicated win than the scoreline suggests, which Amorim made no mistake emphasising after full-time.
The Portuguese tactician was the most animated a United boss has been in the technical area since the peak of Jose Mourinho's theatrics in the first half.
Away from the TV cameras, Amorim aimed his frustrations towards Matthijs de Ligt, Casemiro, Zirkzee and Amad in different moments before United's 34th-minute opener.
On the 25-minute mark, he turned towards the hosts' bench and ordered Mason Mount and Alejandro Garnacho to put on their bibs and head out for their warm-ups.
He hasn't been shy with his substitutions across the 1-1 draw at Ipswich Town and the victories over Bodo/Glimt and Everton. Again, part rotation and part experimentation.
Mount and Garnacho likely would have entered the fray at half-time had Rashford not fired United ahead via a well-worked corner routine courtesy of new assistant head coach Carlos Fernandes.
Rashford's second between Zirkzee's double ensured it was a comfortable afternoon in the end, extending United's unbeaten run to seven games.
However, Amorim's latest five substitutions continued the chop-and-change trend at the dawn of his tenure.
And while they responded to the 39-year-old's early anger with solid performances, Casemiro and Zirkzee could drop out of the team against Arsenal.
Rasmus Hojlund didn't play a single minute after his midweek match-winning brace against Glimt, suggesting he was resting for the trip to north London.
Meanwhile, Manuel Ugarte was similarly impressive on his first start since reuniting with Amorim against the Norwegian champions.
And his defensive tenacity should prove crucial against Mikel Arteta's ever-dangerous side, either alongside Casemiro or in the Brazilian's place.
