You're correct JP, but under Jose Mourinho we went backwards when it came to the medical and Sports science side of the club. And below is the testimony of Dr Robin Thorpe who worked at the club until 2019 in a Head of recovery/regeneration capacity and described the sports science side at the club as one that was among the very best until Mourinho's arrival. No other club had a similar role to the one Dr Robin Thorpe was occupying and hence we were described as being ahead of the competition when it comes to the Sports science side of the club.If I'm not mistaken the one thing that is kind of accepted is that it's not spacious enough. The rest is nonsense because it's constantly revamped and improved. And as you said all managers have been allowed to suggest and get new equipments.
Dr Robin Thorpe:
"We used the monitoring framework up until the first year of Jose Mourinho’s time as manager of United. During his first season the emphasis moved from monitoring fatigue to rehab monitoring."
"I do believe we had created something special in the monitoring of recovery and fatigue, but that wasn’t as much of a priority for Jose, which was obviously his prerogative as manager."
"He allowed us to keep doing it - and in the first year we kept monitoring throughout - but when we realised there were other areas he wanted us to hone in on and get better at, we focused more on a rehab monitoring protocol."
"The monitoring lounge - probably the best monitoring space in the world - that we’d developed under Sir Alex and Louis was turned into a medical room. Looking back, that was disappointing, but adaptability is important for both a practitioner and a department."
"Sports science is part of the process, it’s not THE process. As I said near the start, we’re ultimately there to help the key stakeholders - with the manager or head coach chief among them."
