Nottingham Forest fans are hoping Oliver Glasner can revive their fortunes — and the early signs were good in the Austrian’s first game in charge.It would be unwise to put too much stock in the first friendly of the summer, particularly a game that saw Forest field a different team in each half, but there was plenty to analyse in their straightforward 2-0 win against Notts County at Meadow Lane.So, what did we learn from Glasner’s first match as Forest coach?Positive vibes…This is only Glasner’s first week in charge, but on the training ground, the former Crystal Palace manager has been quick to deliver a clear message to his new squad: the importance of culture.He has told his players that he expects them to set standards when it comes to quality and attitude in training, to put their work ethic first and to believe their approach is one that can bring success.“There have only been positive vibes from him,” captain Ryan Yates said afterwards. “I don’t want to get too excited, but considering he has only been here a week, the information he has given us and that we have been able to take in has been really, really good.Igor Jesus celebrates his goal (Lee Keuneke/PA Images via Getty Images)“He is huge on culture — having a willingness to learn and take on ideas. He wants us to have that (work) ethic every single day, to work and to believe that it is going to work.“We have had some fantastic managers here and it has not worked out. I do not know whether it is the way he speaks to us in meetings or his track record, or a bit of everything — but we already have a special feeling with Oliver.”Glasner was also an enthusiastic figure in the away dugout — and was still busy pointing and gesturing, seemingly trying to make tactical tweaks to his backline, in the final seconds of this win.An early hint on formation?Yes… and maybe no.Glasner has frequently spoken about what he views as the crucial difference between the system and the way his side plays — he places less stock on formation and more on mentality.After the game, he insisted that his decision to play a 3-4-2-1 formation was largely motivated by the players he had at his disposal.“It was just that we had so many defenders available now,” he said. “I do not want to play a defender as a striker because then he cannot show his skills. That is why we decided to play that way.”That may well be true, but Glasner favoured a similar formation in almost all of his games at Crystal Palace.And it was no surprise to see the 51-year-old stick with the approach that helped lead Palace to FA Cup and Conference League successes over the past two years, even if he has insisted he is not wedded to that way of playing.Either way, the early signs were promising. Forest were without Murillo, who is still recovering from the hamstring injury that sidelined him for the final weeks of last season, although he is back doing some work on the training ground. Forest still fielded two Brazilian defenders in the first half, Jair Cunha and Morato, who played either side of Nikola Milenkovic in a back three.Forest had to deal with the imposing figures of Lee Ndlovu and Emile Acquah, who led the Notts County front line with physical presence. But they largely looked comfortable in neutralising the pair.There was a change in dynamic further up the pitch, particularly in the first half. Morgan Gibbs-White and Omari Hutchinson effectively played as two No 10s in that first period, just behind striker Igor Jesus. Gibbs-White’s pass to send Jesus through for the first goal, a composed finish from the Brazilian, was superb.A chance to shine?After the final whistle, Glasner could be seen enthusiastically chatting to Arnaud Kalimuendo by the side of the pitch.The striker spent the second half of last season on loan at Eintracht Frankfurt, who have been keen to make his move a permanent one. But the 24-year-old offered a fresh reminder of his capabilities with a well-taken header for Forest’s second goal, glancing home a cross from Dilane Bakwa.Glasner did not exactly slam the door on a potential exit for Kalimuendo when asked about his future, but he did pledge that the Frenchman — and others — would get an opportunity.Arnaud Kalimuendo will be given a chance under Oliver Glasner (Jon Hobley/MI News/NurPhoto via Getty Images)“Everyone deserves to play and show what they are capable of,” he said. “He had a fantastic game, not just with the goal he scored. He found very good positions between the lines. The transfer market is just heating up, and we do not know what will happen. But right now he is a Forest player and he will get a chance, like everyone else.”Glasner — like the four managers who went before him last season — has spoken positively about the quality James McAtee has shown on the training ground. The former Manchester City attacking midfielder looked neat in a deeper role alongside Yates. If Glasner can find the right role for the 23-year-old, he can still be a major asset.We even got our annual summer look at Omar Richards — and he did not look out of place as a left-sided central defender in the second half, even if another loan move seems more likely than the 28-year-old finally making his Forest debut, four years after signing from Bayern Munich.Ibrahim Sangare and Chris Wood will join up with the squad in Portugal for Forest’s training camp next week following their World Cup duties with Ivory Coast and New Zealand, while Xaver Schlager’s signing as a free agent should also be completed after his RB Leipzig exit in time for him to make the trip. Callum Hudson-Odoi is close to being fit again.But Glasner also seems keen to give everyone else an opportunity to show what they can do in the meantime.
