Michael Schumacher's input into the Mercedes Formula One team may have directly led to the future dominance that the team has had, according to his agent Sabine Kehm.
The German returned to the sport he once dominated in 2010 following a three-season absence where upon he raced alongside future champion Nico Rosberg.
Despite the strong driver line-up and tactical genius Ross Brawn on the pit-wall, the team struggled for three years before Schumacher hung up his helmet on a more permanent basis.
Despite failure to add his personal total of 91 wins, Schumacher plainly left a mark on the team in his wake as the team would go on to win five of the next six constructors' titles.
In an hour-long interview with the F1's "Beyond The Grid" Podcast, Kehm revealed, as per GP Fans: "Very quickly it became very clear that it would not turn out the way that he had hoped for because, in the first year, the resources were not really there and it was clear that they would not be given as well.
"So that was obviously a little bit disappointing, but then at some point it was [decided] 'we have to cope with it and have to go on' and I think Michael fought a lot to convince the right people to really give more money into it and really make it a big team again.
"He really made it very clear that if you want to do it you have to do it really full throttle.
"At the beginning it was a bit undecided, we came back but not really, and they were kind of operating a little bit as a middle team and not really as a top team.
"I think the way that Michael kind of addressed this to some people helped them to really see that it makes no sense to do it like this.
"Already in his last year, you could see that the things were coming and coming and it was quite obvious also to him that if he had stayed another year, that would already be a much better year for him as well."
It plainly worked as his replacement for 2013, Lewis Hamilton, would go on to take four titles in six years in his car in a dominant spell only previously seen between 2000-2004 when Schumacher himself ran Formula 1.
Schumacher's long-term friend and race-engineer Ross Brawn featured on the same podcast the week before Sabine Kehm and supported the claims by describing the lack of development between 2010-2012 as they tried to make financial ends meet.
He also described the incredible work ethic and attention to detail that Schumacher showed throughout his career to develop a struggling Ferrari in 1996 and Mercedes in 2010.
The interviews came as part of a celebration of Michael's 50th birthday celebration.
