Matheus Cunha was seen gesturing angrily towards Manchester United fans as the home crowd made their frustrations clear after their 1-1 draw with rock bottom Wolves at Old Trafford.
Man United were booed off at full-time on Tuesday night after being held by Wolves, who had earned just two points prior to the match.
Footage at full-time showed Man United players heading towards the tunnel, with several fans making their feelings clear after Ruben Amorim's side let more points slip at home.
Cunha, who had been facing his former club, could be seen gesturing in response to the Man United supporters.
Fans in the clip could be heard shouting that the team were 's***' and boos were audible, while another could be heard reacting to Cunha by suggesting the star was getting 'aggy'.
Further images showed that Cunha's frustrations had continued as he walked past the corner flag and entered the tunnel, as he continued to gesture back at fans.
It had proved a frustrating evening for Cunha against the side he joined from in a £62.5million summer move.
The Brazilian international had joined the Red Devils after an impressive campaign with Wolves, where he had scored 17 goals and provided six assists in 36 matches last season.
Cunha has shown flashes at Man United this season, but has contributed just three goals and one assist in 17 appearances.
The draw had seen Wolves earned just their third point of the campaign, with the Premier League's bottom side ending an 11-match losing streak.
It was Wolves first point since the start of October, with the club having only other points coming in draws against Tottenham and Brighton.
Wolves had threatened to earn a first win of the campaign at Old Trafford after Ladislav Krejci cancelled out Joshua Zirkzee's deflected opener.
With Wolves having been cut adrift at the bottom of the table, with Rob Edwards side still 15 points from safety, the draw marked a major setback for Amorim's Man United.
The Red Devils remain sixth in the Premier League, just two points shy of fourth placed Liverpool, but fans have grown frustrated after watching their side drop valuable points again at Old Trafford.
Amorim's side were beaten 1-0 by 10-man Everton at home last month, with the result followed by draws against struggling West Ham and Bournemouth sides.
A 1-0 victory over Newcastle offered signs that Man United may have turned a corner at home, but the draw with Wolves represented a setback.
'If you play for Manchester United, it doesn't matter who is playing or who is on the bench and who is out. You have to perform and win, that is the pressure we have,' Amorim said post-match.
'You can look at the game and the position we put players in trying to manage but we struggle in certain moments.
'When we scored, we could not manage not to suffer in the last play of the first first half - today and in other days. That moment and those details are costing us a lot of points.'
Man United will seek to bounce back when they travel to face Leeds United on Saturday.
