When Oliver Glasner made his shock announcement in January that he was to leave Crystal Palace upon the expiry of his contract in the summer, he said it was for “a new challenge”.That set off a chain reaction of emotional outbursts directed towards the club’s hierarchy and, later, the supporters which led his relationship with some Palace fans to breaking point, only to achieve redemption in Leipzig when he guided his team to success in the Conference League.There was goodwill again. “I came as a stranger and now, after two years, I feel like I am a south Londoner,” he said before undertaking the lap of appreciation after Palace’s final game of the season against Arsenal. Yet few, if any, anticipated that the new challenge of which he spoke would come as manager of Nottingham Forest, for whom he joined on Monday. “Our aim is to build a team that can help take the club to the next level in the years ahead and that our supporters can be proud of,” he said.“From my very first conversations with the owner and the leadership team, it was evident to me that they have a clear vision for this football club and complete trust and belief in me and my staff to build a strong future together over the long term.”Glasner brought unprecedented success to Palace, and following that will be tough at Forest. But what can they expect from him at the City Ground?A focus on the here and nowThe Austrian is not especially reflective or sentimental. He insists that if you believe something will happen, then it will. That attitude is likely something that came from surviving a brain haemorrhage, suffered while he was playing at SV Ried where he spent the majority of his playing career.Appointed as manager in 2014, he went on to make a huge impression as manager in that small town in Upper Austria. it quickly became apparent he was ready for bigger things. With an intense focus on running and data to back it up, the club could not provide the facilities for that to prosper further.In 2015, a move to arch-rivals LASK, where he also briefly played, saw Ried fans hang effigies of him as a result, although he was eventually forgiven. Twice he won promotion, twice he qualified for Europe. That led to him joining German Bundesliga side Wolfsburg in 2019 where he impressed before moving to Eintracht Frankfurt in 2021 and winning the Europa League at the end of his first season, only to then leave under a cloud at the end of the 2022-23 campaign.

He typically burns relationships with the hierarchy, the supporters and/or simply sees out his contract before seeking something fresh.He has a fascinating personality and has many catchphrases. “Intrinsic motivation” is among the most important to him; everyone must want to achieve for themselves, they cannot be motivated by external factors, otherwise they will not succeed.But it is ‘Nicht in Problemen zu denken, sondern in Loesungen’ (or NIPSILD) that is most prominent — a German phrase which translates roughly as ‘Don’t think in problems but solutions’. Glasner repeatedly speaks about finding solutions to problems. It is fundamental. He is very intense, demanding, emotional and, by his own admission, impatient.
