Ralf Rangnick's revolution at Manchester United is barely a month old yet his fingerprints can already be seen wherever you look at the club.
One of Rangnick's first acts was to bring a sports psychologist to Old Trafford, with Sascha Lense, a close confidant during his tenure at RB Leipzig, joining United's backroom staff.
Lense's appointment presented a number of pertinent questions, from the benefits of employing a sports psychologist and the overall objective, to the willingness or reluctance of players to get involved.
Rangnick took time to explain to the press the benefits that the new addition of a sports psychologist would bring to United.
"I wouldn't say I was surprised,I know from Germany there are quite a few clubs who do not work with a sports psychologist. But, for me, it is absolutely logical.
"Every club has different experts for goalkeeping, for physical performance, for different areas of the field - defence, midfield, offence. The team of experts at some teams is probably bigger than the number of players in a squad.
"If you then consider the brain, the head, the way players, staff members or coaches think is the most relevant one, then for me it is only logical to have the best possible expert from that area in your staff.
"This is what it's all about, to help the players think the right things and not think the wrong things. To develop players, the brain should help the body perform at the highest possible level.
"This is part of the jigsaw, of the puzzle. It's important for any top club, and Manchester United is one of the biggest clubs in the world - have the best possible people, and they should at least have all those little pieces available.
"It shouldn't be the case that in certain areas we don't have anyone. I strongly believe that every club in the future should have someone in this department," Ralf noted.
While this appointment is not expected to elevate United into title contenders overnight however it does provide Rangnick's players with the tools to shoulder the lofty expectations that come with playing at one of the biggest clubs in the world, and focuses, first and foremost, on the personal rather than the professional.
"Players at this level are under pressure to deliver and perform at the highest possible level," Rangnick added. "At times they might need help and might need somebody to speak to.
"That should not always only be the manager or head coach. It's important for the players to know there is a neutral person, an expert, to whom they can address in situations where they might need a helping hand, or even somebody to just listen to them.
