As the match entered injury time, it looked to be heading for a scoreless draw until Marcus picked the ball up at the edge of the box in injury time, drove at the Midlands club's back line and fired a shot at goal.
Thankfully, a deflection off opposition defender Roman Saiss managed to unsettle Rui Patricio in the away goal and ensured the ball found its way into the back of the Stretford End net.
Speaking after the game, Marcus explained what influenced his decision to run at Wolves defender Rayan Ait-Nouri, before smashing in the decisive effort.
