Roundtable understands that Steve Holland, Michael Carrick's former assistant coach at Manchester United, became disliked across the span of his Old Trafford tenure. 

When he first joined, he was highly regarded, especially from a tactical point of view. The former Chelsea assistant played a key role in Manchester United's impressive run under Carrick last season.

Sources say Holland sometimes clashed with his players, and his instructions were not easy to follow. He remained stubborn when United were losing, with some describing him as “difficult to work with”.

One source described him as “extremely arrogant” and not a popular figure at Carrington since his arrival earlier this year. As United's bad form continued this season, Holland was seen looking more miserable around Carrington on a day-to-day basis.

Roundtable also understands that Bruno Fernandes’ comments in the post-match Como interview were directed largely towards Holland, not just Michael Carrick. Holland then pushed for the captain to be dropped after the Champions League tie, which happened.

When things go right (as seen last season), Holland's qualities shine through his tactical knowledge and experience. However, when things start to go wrong, Holland's issues surface, as seen this season when United's bad form spiralled.

All of Michael Carrick’s first-team coaching staff, excluding assistant goalkeeper coach Connor King, were sacked on Thursday morning.

Some staff believed that Jonathan Woodgate, another of Carrick’s coaches, lacked the experience or qualities to be a first-team coach. While this may be opinionated, and it's easy to say now that he's gone, Woodgate has never managed at any level remotely close to the demands of United.

There was a lot of sadness today at Carrington as all of Carrick's backroom staff said their goodbyes and left. Travis Binnion was very well liked internally by many staff members, as well as by goalkeeping coach Craig Mawson.

Mauricio Pochettino looks set to replace Carrick at Manchester United, with Simon Peach reporting that an announcement could come within the next 24 hours.

It has been widely reported that the Argentine has a large coaching staff that could follow him to Manchester. 

Pochettino looks set to coach the USA national side against Haiti, moving to Old Trafford just days before the trip to Anfield after the international break. 

It has been reported that Luke Shaw and Marcus Rashford could return to the Manchester United squad against Liverpool after the international break. 

The Telegraph have reported that Mauricio Pochettino has "always loved" Rashford and is excited to get the chance to work with the Englishman at Old Trafford. 

Rashford could become the first-choice left-winger, though he has to compete with Matheus Cunha and Patrick Dorgu on the left flank. 

However, Dorgu could become a left-back under Pochettino, given that he is known for high-flying full-backs, regardless of the team he coaches. At Tottenham Hotspur, this was Kyle Walker, Kieran Trippier, and Danny Rose, but it continued with Antonio Rüdiger and Sergio Dest at the World Cup. 

Pochettino has also been known to favour all-action central midfielders, like Moussa Dembele and Tyler Adams, but that could be an issue until the January transfer window. Carlos Baleba would be the first choice for that role, but he remains out with a hamstring injury after picking up a hamstring injury against AS Roma. Andrey Santos could also be trialled, but that is not his natural playstyle. 

The new head coach will not have an easy start in Manchester, with games against Liverpool and Sporting CP before his first home game against Brentford, the final game of November.
