Phillips’ £42 million move – which could rise to £45 million – has left a spiritual and physical hole in United’s midfield.
The influential England international will be greatly missed at Elland Road, not least for his impact on the pitch, but attentions have now turned to sourcing a replacement.
Adams initially broke through under Marsch at New York Red Bulls in Major League Soccer before sealing a move to the Bundesliga side whilst still a youngster.
There, the American was tutored by Marsch where the Leeds head coach initially worked as an assistant to Ralf Rangnick, before taking the top job at Red Bull Arena last summer.
Speaking to ESPN earlier this year, Adams revealed his experience of working with Marsch, discussing the 48-year-old’s man-management style.
"I think as an American, you have to earn your respect wherever you go. When you go to Leeds and you come after a manager like Marcelo Bielsa, it's obviously a big name, so it's not going to be easy, but for me, I'm just really grateful for Jesse giving me an opportunity to become a professional [at New York], he kind of groomed me and gave me my first opportunities to play the professional game. He's very heart-to-heart with you, he's upfront and honest with you and I think he'll do well there [Leeds],” Adams said in March of this year.
“[Man-management is] super important, super important. I think that when you can have a good connection with your players, you know, they want to battle for you. They want to fight for you on the field every week. And so, being able to sit down and talk to them whether it's about football about life, that connection is important.”
