Bayern Munich's Jamal Musiala celebrates after setting up the goal that made his side's fourth goal of the game during the German Bundesliga soccer match between FSV Mainz 05 and Bayern Munich at Mewa Arena. Torsten Silz/dpaBayern Munich travel to France for their Champions League semi-final against Paris Saint-Germain brimming with confidence after an extraordinary 4-3 Bundesliga comeback victory at Mainz and with Jamal Musiala nearing his top form again.Germany star Musiala scored along with Nicolas Jackson, Michael Olise and Harry Kane as Bayern overturned a 3-0 half-time deficit for a stunning victory on Saturday.They had already clinched a latest Bundesliga title a week ago but still showed class and morale when it mattered, like on previous occasions this season.Huge mentality"I love this kind of mentality," coach Vincent Kompany said."We celebrated like we’d saved ourselves from relegation.
When you need a miracle at the end of the season, you can’t start from nothing. You have to gain the feeling and the belief, and that was always there today. That’s the basis for me.”Musiala said: “It’s a good thing for all of us that we haven’t let our mentality drop despite winning the title."We could’ve easily lost 3-0 and carried on, but the fact we still have the hunger to turn the game around, to celebrate as if we’d won the title, is a good feeling.
We need this feeling for the coming weeks if we want to win more.”Musiala shines and scoresMusiala missed Bayern's 2-1 league stage win in Paris in autumn as he was still recovering from a leg fracture and dislocated ankle he sustained in their quarter-final meeting in July at the Club World Cup in July which PSG won 2-0.He returned in January, missed a few more weeks due to a pain reaction in the injured ankle but is now nearing his best again and was all smiles on Saturday.“The celebration, the smile – when an attacking player shows that, everything’s released. Then everything’s all right. It’s the first time that Jamal is feeling this freedom again,” Kompany said.Best teams in EuropeBayern have lost only two of their 48 matches across all competitions this season as their treble big continues, in the Champions League at Arsenal, who play Atletico Madrid in the other semi, and against Augsburg in the Bundesliga.PSG are the defending champions and boast stars including Ousmane Dembélé, Khvicha Kvaratskhelia and Vitinha but the matches have mostly been tight and Bayern also won their meeting in the 2020 final.Bayern midfielder Leon Goretzka said that the tie brings together "the two best teams in Europe" and Bayern will also like their chances having eliminated record winners Real Madrid in the quarter-finals.Big boostThe way they won in Mainz will give them an additional push for Tuesday in Paris and the following week in Munich, players and officials agreed."This team is very special, this team spirit, this mentality, this character – it’s really one of a kind. This gives us a lot of energy for Tuesday," sporting director Christoph Freund said.
