Bruno Fernandes is facing criticism for his Manchester United outburst

Gabby Agbonlahor has slammed Manchester United captain Bruno Fernandes after he hit out at Michael Carrick. The Portuguese took aim at the head coach in the aftermath of their 4-1 defeat to Como in the Champions League.

Fernandes became the latest high-profile United player to lambast a member of the club after Lisandro Martinez's incendiary comments towards the hierarchy following last week's 2-0 defeat at Atletico Madrid.

Carrick is under increasing pressure with the defeat to the Serie A side stretching their run without a win to seven games in all competitions, meanwhile deeper problems and friction within the squad is coming to the fore.

The 45-year-old has been facing scrutiny since before the international break last month but their form hasn't turned a corner. Agbonlahor became the latest former player to lament Fernandes.

He said: "Don't get me started on him. He is a disgrace... Manchester United looked like they were off the cuff and weren't interested, it's not just Carrick by the way.

"He's absolutely killed the manager. Starting with Bruno Fernandes, I've been saying it for years, he's showing himself when the going gets tough at Manchester United now, how is he the captain of that football club?

"He was a disgrace, he was giving the ball away, throwing his arms about, Tielemans tried a cross and because it didn't pick out Fernandes, he's throwing his arms up, pointing fingers at him, he'll be the player in the dressing room that the players dislike.

"When he got dragged at 60 minutes, I was like, 'fair play to you Michael Carrick, if you're going to go down and get the sack, you're going down your way.'

"Fernandes deserved that for weeks, he's done nothing. You're giving the ball away then taking it out on your teammates, what a horrible teammate you are."

Martinez would later apologise to Carrick and members of the United hierarchy for his comments in Madrid. However, the fallout from the defeat to Como is only just beginning with reports that Matheus Cunha was involved in a heated exchange with the United boss.

Time is ticking for Carrick to turn around their fortunes with four matches remaining before the next international break.

Bournemouth visit Old Trafford on Sunday before a trip to Xabi Alonso's Chelsea next weekend. They have back-to-back home matches against Roma and Aston Villa before the interval but standing seven matches without a win, reports over potential successors are intensifying.

Fabian Hurzeler, Antonio Conte and Julian Nagelsmann have all separately been linked with replacing Carrick. Nagelsmann appears to be emerging as the standout contender having left his position at Germany in the summer.
