Manchester United interim manager Ralf Rangnick has expressed his delight at adding two coaches to his backroom staff.
The German confirmed the appointments of Chris Armas and Sascha Lense on Tuesday afternoon, although they won't start work until after the game against Young Boys.
The Red Devils final Champions League group stage fixture takes place at Old Trafford on Wednesday evening.
Both coaches worked with Rangnick when he was in charge of Red Bull's footballing activities between 2012 and 2020.
Armas, who will replace Michael Carrick at Old Trafford following his departure last week, was part of the coaching team at New York Red Bulls for five years.
Should Ralf Rangnick make more changes to his backroom staff? Let us know in the comments below!
Lense, meanwhile, was a sports psychologist at RB Leipzig between 2015 and 2018 and will hold a similar position at United.
Speaking to the club's website about the appointments, Rangnick explained what they will bring to the dressing room.
“Sascha Lense, who we employed as a sports psychologist, or a mental coach – whatever you want to call him – we worked together for three years at Leipzig, in the year I won promotion myself," said Rangnick.
"And, in the two following years, he was working together with Ralph Hassenhuttl and Zsolt Low. So the fact that I know him has been of great help.
"He's a former Second Division player himself. He's very much working on the field, on-hand, not in theory, not in putting anyone on the red sofa or whatever the cliches with these kind of jobs elsewhere.
"He should help everybody: the team, the players, even the coaching staff. To help the brain, to assist the body and not to work against it. I couldn't put it probably in any other words than that.
"It's helping, again, to train the brain, thinking the right things, always stay, in a way, on the bright side of life, if I may say so. That's his job."
Several top clubs have added a sports psychologist to their backroom staff in recent years, with Liverpool appointing Lee Richardson in November 2019.
"He's a fantastic person, which is important because then I don't have to convince the boys to talk to him, it's easy," said Jurgen Klopp when discussing Richardson.
"He is a really, really interesting person and so the boys enjoy, for sure, that he is around and when you need him, you can use him."
On Armas' appointment, Rangnick added: "Since Michael is no longer there for me, it was clear that we need somebody.
"The thing about Chris, again, is that we've known each other for six, seven years. He was the assistant coach of Jesse Marsch at the New York Red Bulls.
"He's then become head coach at the New York Red Bulls, and then at Toronto. So he's well acquainted with the proactive kind of football we want to play also in the future.
"And, therefore, I'm very happy to have him on board."
