Bruno Fernandes is one of a number of senior players at Manchester United who are losing faith in manager Ole Gunnar Solskjaer, according to recent reports.
The former Sporting player arrived in January to much fanfare and helped turn the club's fortunes around, with his performances catalysing a run to take them to third in the 2019/20 Premier League.
However, they have made a dreadful start to the new season, losing on the opening day to Crystal Palace, very fortunately defeating Brighton, and then being destroyed 6-1 by Spurs.
At half-time in the defeat by Jose Mourinho's side, Man Utd were trailing 4-1, with Fernandes allegedly shouting and complaining about his manager's tactics in the changing room at the break.
He was brought off before the second half for Fred.
The dust hasn't settled, though, with Duncan Castles reporting on the Transfer Window Podcast that Fernandes believes Solskjaer is holding United back.
"There is a sense from top level players who have had experience with some of the best coaches in the world that he (Solskjaer) is not world class or top of his field," Castles said.
"We saw in Man Utd's last game that he was substituted at half-time. There has been reports about what he was saying on his way into the dressing room at half-time.
"He was shouting 'we are supposed to be Man Utd, this shouldn't be happening' and that he was questioning Solskjaer's tactics.
"That was one of the things contributed to him being replaced by Fred.
"I'm hearing that Fernandes' opinion is similar to that of other senior players. He does not think that he (Solskjaer) is strong enough to manage the squad and doesn't have capabilities to push the players forward."
Fernandes is also apparently unhappy with the club's transfer business over the course of the summer. Although Donny van de Beek was recruited, the Old Trafford side had their eye on the likes of Jadon Sancho and Ousmane Dembele, too.
In the end, they settled for the deadline day signing of free agent, Edinson Cavani, as well as left-back Alex Telles for the senior squad.
"I understand that Fernandes is angry with the club in the sense that what they did in the summer window did not cohere with expectations of what would happen when he arrived," Castles added.
United are currently 16th in the Premier League, though do have a game in hand over most other sides due to starting their league season a week later.
