Manchester United legend Sammy McIlroy believes that getting the right assistant manager for potential new manager Erik ten Hag's is vital for the success of the club.The Red Devils are reportedly on the brink of naming the Dutchman as the club's next manager, with ESPN claiming his appointment is set to be finalized.According to McIlroy, that is not the only decision that Manchester United need to get right this summer, with the Scot stating the importance of bringing in the right assistant coach.He told TalkofTheDevils:“I think it’s so important that he gets his number two right.”He continued:“I don’t think he has to pick one just because he’s been a fantastic footballer at Manchester United. It’s very important that his backroom staff are bang on with him. With Ole there were three or four (former United players) behind the scenes, so if maybe one or two of them are kept on to let the new staff know what United is all about, I think that’s important, I really do.”A host of names have been linked to the role.Dutch journalist Marcel van der Kraan told Sky Sports that the 52-year-old is eager to have a Dutch coach with United connections join his backroom.Robin van Persie, Jaap Stam, Steve McClaren and Rene Meulensteen, who all boast those credentials, are the names reportedly in contention for the role.Sky Sports News@SkySportsNews🗣️ "He's sounding out one or two members in Dutch football with a background at Manchester United."Could Ruud van Nistelrooy or Robin van Persie join Erik ten Hag if he gets the job at #MUFC? 1:07 PM · Apr 6, 2022899108🗣️ "He's sounding out one or two members in Dutch football with a background at Manchester United."Could Ruud van Nistelrooy or Robin van Persie join Erik ten Hag if he gets the job at #MUFC? 👀 https://t.co/OB4dHrTUzUOne coach that looks set to depart the club is Mike Phelan.
