Rasmus Hojlund directed his frustration towards Manchester United team-mate Alejandro Garnacho after the Argentinian failed to find him running into space in the box.
The United striker was desperately searching to get his FA Cup account up and running against Newport and lead the attacking line while being flanked by both Garnacho and Antony.
Erik ten Hag's side eventually secured a valuable 4-2 victory at Rodney Parade and progression to the FA Cup fifth round, despite initially having their two-goal lead wiped away.
Brazilian winger Antony restored United's lead in the 68th minute with a strike from a tight angle and Hojlund was left fuming just 12 minutes later when he was denied the chance to get in on the action.
