It led to social media users donning him "Harrydinho," perhaps a more affectionate nickname than Maguire has previously been subjected to during periods of his six years at Old Trafford.
"It's brilliant ... I'm sure there are a few nicknames out there for me," Maguire told TNT Sports when informed of the nickname.
"It was nice to do a bit of dribbling out there and obviously put in a great cross," he added. "There was a lot of bodies in the box so they must have trusted me to get that cross in. It was a nice feeling and Casemiro put it in the back of the net, it was a great header in the end."
Harry Maguire has welcomed his new Brazilian-inspired nickname after the centre-back's unexpected trickery on the wing helped put Manchester United on course for a stunning 3-0 win at Athletic Club in the first leg oft their Europa League semifinal.
Maguire found himself in unfamiliar territory out on the right wing but looked right at home as he twisted and turned an opposition defender before delivering a pinpoint cross that Manuel Ugarte flicked on for Casemiro to find the net and open the scoring in the 30th minute.
