Actually there is nothing different in my opinion, both Toulouse and Werder Bremen (Bundesliga) because both of them are in the lower team category or outside the top 10, of course it will be difficult for these players to shine with their interested clubs. Another thing if the team looks at him like Lens, Marseille he maybe younger to shine because have a club ready to push him
But in fact, Schmidt also did not really play for Werder Bremen last season, because Schmidt last season was loaned to a club playing in the 2. Bundesliga. But indeed, if Schmidt next season will really play at Toulouse, maybe it will also be an increase in level for Schmidt. Because maybe, Schmidt can get a better place at Toulouse and not be a player who is only on loan and or only on the bench. Also, in fact last season Toulouse won the Coupe de France and of course, even though Toulouse didn't finish in the top 10, but Toulouse still managed to show their quality by winning the Coupe de France last season. At least it remains an achievement for Toulouse which basically, Toulouse is not really a favorite to get it. So yes, at least that is also the reason maybe Toulouse could be the exact club for Schmidt to increase experience at a relatively young age.
