Receiving a pass from Bruno Fernandes inside the Arsenal half, the Reds' no.10 still had work to do but after cleverly nutmegging Arsenal midfielder Thomas Partey, he unleashed an effort that flew past Aaron Ramsdale to hand us the initial lead in our eventual 3-2 defeat.
It was his first-ever strike at the Emirates Stadium, and hopefully there will be more to come from Marcus against the current Premier League leaders.
January proved to be another stellar month in front of goal for Marcus, as he found the net seven times in total.
His tally for the season now stands at an impressive 18 goals in 31 appearances as the England international, who was also crowned Player of the Month by United fans and the Premier League, continues to go from strength to strength under Erik ten Hag.
