As the hosts prepared to take a four-goal lead into half-time, the Swedish striker was approached by a pitch-invading doppelgänger, who managed to have a quick word with his hero, according to the independent.co.uk.
Images of the incident show a young man who bears a remarkable resemblance to Ibrahimovic talking with the striker, only to soon be rugby tackled by a lone security guard.
Ibrahimovic appeared to enjoy the brief meeting with his lookalike, but he will perhaps be slightly disappointed not to have scored on the day at Old Trafford.
Despite putting in an impressive display and going close with a first-half volley, the former Paris Saint-Germain failed to increase his league tally of four.
Goals from Chris Smalling, Juan Mata, Marcus Rashford and Paul Pogba blew Claudio Ranieri’s Foxes away in the first half and all but sealed the three points.
