Ten people have tested positive for coronavirus in more than 1,700 tests carried out by Germany's professional soccer league (DFL) at its 36 clubs ahead a planned resumption of full training, it said on Monday.

The DFL, which tested players and coaching staff at the Bundesliga and 2.Bundesliga teams, did not identify those who had tested positive or their clubs and said the cases had been reported to health authorities.

"The appropriate measures, for example the isolation of the affected persons, were taken immediately by the respective clubs in accordance with the specifications of the local health authorities," it said.

The German league has been suspended since mid-March due to the coronavirus pandemic and the government is expected to decide on Wednesday on a potential resumption.

Bundesliga side Cologne announced three positive tests on Friday and placed the individuals in a 14-day quarantine while the rest of the squad continued training.

The DFL has submitted a health safety plan for games without spectators which includes regular testing of players but no quarantine for entire squads in cases of positive tests.

However, German Interior Minister Horst Seehofer said on Sunday that he was in favour of full team quarantine in cases of positive test.

Teams were allowed to resume training last month, with players divided into small groups, and the next stage would be for full team practice sessions to begin.
