Ruud van Nistelrooy enjoyed a winning start to his caretaker spell in charge of Manchester United to reach the League Cup quarter-finals on Wednesday as Leicester were beaten 5-2 at Old Trafford.
Arsenal and Liverpool were among the other sides to book their place in the last eight, but Chelsea were beaten 2-0 at Newcastle.
A United legend as a player, Van Nistelrooy was thrust into the role of interim manager after the Red Devils sacked Erik ten Hag on Monday following a dreadful start to the season.
Sporting Lisbon boss Ruben Amorim is the man the English giants have targeted to take over but are still in negotiations with the Portuguese champions to agree on compensation for the 39-year-old.
According to reports in Portugal, Amorim will remain at Sporting for the next three matches before completing his move during the November international break.
Van Nistelrooy said before the game that United “can be unstoppable” when “players, staff and supporters pull together” and they cut loose by scoring four times in a thrilling first 45 minutes.
