Rosler was appointed Leeds United head coach yesterday.
Rosler arrived at Elland Road to oversee a new era at Leeds, in which he intends to bring stability and progression after a turbulent season.
Under Massimo Cellino, Rosler is the fifth head coach in under a year, but he seems the wisest choice on paper, having great experience of English football, and proving himself with Brentford - although he did struggle with Wigan.
When a new manager comes in, there are always worries about the state of the current squad, with some players cast out for no other reason that not being in favour at that moment in time.
The biggest losers at that time of upheaval are usually academy players, who may have prospered under the previous regime, before the new manager favours experience over youth.
This certainly could be the case at Leeds, with Neil Redfearn truly establishing a number of young players in his reign, with the likes of Lewis Cook, Alex Mowatt and Charlie Taylor all impressing this past season.
There are fears that Rosler could arrive at Elland Road and seek to change the squad in his image, which may involve brining in experience, but if his time at Brentford is anything to go by, Leeds fans have nothing to worry about.
When Rosler left the Bees, the average age of the squad he had built was 22-years-old, three years younger than the average age of Leeds’ current squad.
So not only does he like a keen focus upon youth, the same as Redfearn, but he actually built a competitive squad that was younger than that seen at Elland Road this term.
It bodes well for not just the current make-up of the squad, with many of the best performing players being young stars, but also for the future of the team, and the potential establishment of people such as Kalvin Phillips, who made his debut this season.
If Rosler can find some stability at the club, and remain in a job for more than a season, he should be able to start developing a side in his image, and that is a truly great thought for Leeds United.
