Manchester United jumped to 12th spot on the Premier League standings with a 1-0 win over Fulham on Sunday evening.
Ruben Amorim restored Andre Onana, Manuel Ugarte and Rasmus Hojlund following Thursday's UEFA Europa League win over Rangers.
Fulham provided the lion share of forward momentum through the runs in the wide channels by Alex Iwobi and deep in midfield by Sander Berge.
There were no shortage of chances though where Raul Jimenez came slightly in to the near side of the six-yard and dragged beyond the top corner from a tight angle.
Amorim's men gathered ground on the back of the underwhelming spell, but amidst all intends and purposes couldn't trouble the man in the opposite goal Bernd Leno.
The bright spell carried over to the second period where a low penetrative strike from Bruno Fernandes following a free-kick hit the side-netting.
It remained a clash of small margins with little from either side shown in the way of clear-cut chances nor sustained attacking fortitude.
That's what the Red Devils looked to change after turning focus to the substitutes bench to bring on Dutchman Zirkzee in place of Danish counterpart Hojlund.
Fulham pushed tirelessly later on and nearly had the front with a powerful strike from the area by Amadou Traore, but he went way over the top.
Sense of calmness remained on the side of United who went ahead when Martinez raced further forward to meet a loose ball and powered in the top corner.
Danish international Joachim Andersen nearly levelled it up with a pin-point header from a corner, but substitute Toby Collyer was on hand to clear from the goal-line.
Youngster Amad Diallo, who've been revived in recent times, looked to have settled matters in additional time but was deemed offside by the overall officiating team.
The situation didn't bother the Red Devils who picked up the win regardless and moved into 12th spot on the table.
