Bayern Munich will be huge favourites to win next season's Bundesliga after sealing a double swoop for Renato Sanches and Mats Hummels.
However, fans have slammed the German league in the wake of Hummels' move from Borussia Dortmund, attacking a perceived lack of competition in German football.
His signing has been on the cards for some time, but many seem disappointed that Dortmund's chances of winning the title next season have already been dented.

Hummels, who was born in Munich, was at Dortmund for eight-and-a-half years but made it clear he was unhappy with their initial reluctance to yield to Bayern's demands.
Fans slam German football
He will join Carlo Ancelotti at the Allianz arena next season, with the Italian taking over from Pep Guardiola at the end of the current campaign.
As for Dortmund, they will be left to rue another of their key players taken by the giants. Financially, they are dwarfed by Munich's capabilities, and that has been a telling factor in dealings between the two clubs in recent years.
Robert Lewandowski and Mario Gotze also went the same way while Jurgen Klopp was still in charge of BVB, and many football fans have been quick to deride the Bundesliga as lacking competition due to Bayern's dominance.
The 2013 Champions League final was heralded as the Bundesliga's ultimate achievement, pitting Dortmund and Bayern against each other at Wembley of all places, a condescending statement to English football that Germany's system of youth development and fair pricing was winning the battle for European dominance.
Now, that could not be further from the truth.
In 2012, Dortmund president Uli Hoeness explained why season tickets cost the equivalent of just over £100: "We do not think the fans are like cows, who you milk."
As a club, they have been admired, even if not replicated, from afar. Yet, their ethical approach may not be paying off, as Bayern continue to flex their financial muscles.
A predictable Bundesliga
And it is not just Dortmund who could suffer. If Bayern's dominance threatens to weaken the competitive nature of the Bundesliga, they could find themselves in a similar situation to Paris Saint-Germain, who are often accused of failing to make waves in Europe because they are insufficiently tested in Ligue 1.
This season, it is La Liga who will be boasting of an all-Spanish Champions League final, while the Premier League has provided the biggest shock of all by presenting lowly Leicester City as its champions. German football is unlikely to have anything like that kind of excitement next season.
If this trend continues at its current rate, the Bundesliga threatens to become tiresomely predictable.
