Joachim Low discussed the Bundesliga's quality since the league's return behind closed doors.
"You also have to get used to a bit of football without the excitement that the fans provide. On the other hand, I am positively surprised by the high level of motivation from the players and teams, the attitude and also the way of playing," said Low.
Low added that he believes that the Bundesliga is the top league in Europe.
"You can tell that the players want to compete again, to battle, to score goals, to avoid [conceding] goals.
"This has also had a positive effect for me, that the players came out of such a long break so motivated and look as if they are playing in a stadium with 80,000 spectators," added Low.
