The German Football League (DFL) confirmed on Friday that all Bundesliga and 2. Bundesliga matches have been cancelled until at least April 2.

That followed an earlier announcement that games would go ahead as planned behind closed doors this weekend, leading to criticism from Bayern Munich star Thiago Alcantara.

Bayern president Karl-Heinz Rummenigge defended the DFL's initial decision to play one more round of fixtures, warning of the impact to smaller clubs if the season ended prematurely.

And Watzke agrees "other approaches" should have been taken, with clubs set to meet on Monday to discuss further postponements

"The Presidium of the DFL has made a decision that needs to be respected - regardless of the fact that there would have been other approaches," he said in a club statement.

"We all have to do this together in solidarity and discuss the corresponding derivations on Monday. 

"Nevertheless, it also applies – depending on what will be decided on Monday – that German professional football is in the greatest crisis in its history. 

"It is to be hoped that the Bundesliga clubs have built up so much substance in recent years that everyone will survive this crisis. 

"An existential threat to Borussia Dortmund can be excluded according to everything we can assess today."

Dortmund, who were due to face bitter rivals Schalke on Saturday, are second in the Bundesliga and four points adrift of leaders Bayern.

PSG unveiled Messi on Wednesday following his free transfer move from Barcelona on a bumper two-year deal.

Watzke, who has had to ward off strong interest in Dortmund's prized asset Erling Haaland this off-season, said Qatari-owned PSG's economic position was unfair.

“It is a fact that PSG has more economic resources than 85 per cent of other European teams," Watzke said as reported by L'Equipe.

"It is clear that this is an unfair competition that has already been rife for too long but I am by no means jealous.

"Frankly, it wouldn't be my cup of tea to have to kneel down every fourth morning in front of the Emir of Qatar."

PSG have signed Messi along with Georginio Wijnaldum, Sergio Ramos and Gianluigi Donnarumma on free transfers this off-season, bumping up their player wages.

The Parisians also spent €60million to sign Internazionale full-back Achraf Hakimi, having purchased Mauro Icardi for the Nerazzurri 12 months ago for €50m.
