According to the official information released by Manchester United, Manchester United first-team coach McNaugh left the team, and his new stop is League One side Ipswich, who will become the team's manager.
After the arrival of the new coach Lonnick, although Lonnick said that he would only bring a small number of coaching team members, as the saying goes, a day is a courtier.
Carrick chose to leave with guilt for Solskjaer after completing the transition task perfectly, and his actions were praised by the fans.
The assistant coaches McKenna and Ferran who continue to stay have been questioned by the outside world as to why they did not choose to leave. With McKenna's departure, Ole Gunnar Solskjaer has left only legendary assistant coach Felan in United's core coaching circle.
Unlike Carrick, McKenna's departure came after he had already found his next home. He will travel to Ipswich to replace former head coach Paul Cook, who spent nine months at Ipswich and was fired for poor performance.
Ipswich is currently 12th in the table, with just seven wins in 22 games, and Ipswich hopes the change of manager will bring a pick-up in results.
McKenna started at Manchester United in under-18 youth teams, where he led the team to the North Division of England title.
Mourinho, then Manager of Manchester United, saw the light and promoted him to the first team. McKenna has supported four managers at United, namely Jose Mourinho, Ole Gunnar Solskjaer, Carrick and Ronnick.
McKenna's departure highlighted Mourinho and Ole Gunnar Solskjaer, who paid tribute to them. "I will always be grateful to Mourinho and Ole Gunnar Solskjaer, I have learned a lot in the last four years and am delighted to be part of this team," he said.
The team's football director, Mutaf, also thanked McKenna for his past contributions to Manchester United, saying: "McKenna is a very talented player and his time at Manchester United has been a real asset for the club. Now he has the opportunity to forge his own path as manager and everyone at Manchester United blesses him."
For Lonnick, McKenna's departure will not affect the preparation of the first team, after his new coaching team members Armas and Sasha were already in place. After McKenna's departure, Armas will also become Lonnick's first assistant coach.
Lonnick is expected to continue to recruit to complement his coaching staff in the coming weeks.
