Sure, in the first place it's Kloop's views and ideas but also Klopp's job in Liverpool is based on data that he's getting from these guys:

Pre-match, there’s a set of reports that James [French] and Greg [Mathieson] put together and then post-match there’s a similar thing that Harrison [Kingston] and Mark [Leyland] put together,” he describes.
“What we’ve built is a platform where the analysts can either look at the opposition analysis or post-match analysis from our point of view, so we’ve got expected goals models and
expected possession value models that are linked to video to say: ‘This is what we thought was a dangerous situation.’
“We rarely work directly with the coaches, but the analysts’ department have got access to all of our stats resources and they use those in their reports and meetings.”
But while they may not share regular, day-to-day contact, those in Graham’s department feel connected to the coaching staff - thanks in no small part to Jürgen Klopp’s open-minded, inclusive style of management.
“Jürgen is very open and receptive to our area,” Graham notes.
“Just the fact that he is open to it and intuitively understands the numbers, that’s enough. And if there is anything in particular that needs addressing, we’re there for the coaches. We’ve done one-off bespoke pieces of work where they’re concerned about a particular area of play or want to know something about travel before a game and whether that affects performance.

Same story with Pep
As he came to Bayern, the first thing he said was: “The match analysis department is the most important department for me.” The second thing was: “I see a big part of my work in the auditorium.” The auditorium is the place where he has video sessions. If you want to bring your ideas to the pitch, you have to use these technologies and you have to use match analysis.
