German soccer has so far avoided major pitfalls in three days of games after a two-month suspension for the coronavirus pandemic.

Some of Leverkusen's players clustered together after scoring in Werder's empty stadium, rather than opting for the league's recommended celebrations of minimal physical contact.

Werder were without one player who was isolating at home after someone in his personal life tested positive for coronavirus, despite the player testing negative for the virus.

The Bundesliga faces its next test this week as players return to live at home before the weekend's games.

Teams spent the seven days leading up to their first games in a group quarantine in hotels, but that was a one-off.

Both fifth-placed Leverkusen and Werder kept up their form from before the break, with the visitors extending their unbeaten run to six to close in on the Champions League places, while second-from-bottom Werder remained stuck in the relegation zone.

The game marked the league debut of Florian Wirtz, who at 17 years, 15 days became Leverkusen's youngest-ever player and third youngest in Bundesliga history.

The first three goals came in the space of five minutes.

Kai Havertz headed Leverkusen into the lead in the 28th off a cross from Moussa Diaby, but Werder soon hit back when Theodor Gebre Selassie deflected a corner into the net.

Werder's defence failed to mark Havertz for the first goal and did so again for the second as he headed in at a free-kick.

Leverkusen made sure of the win in the second half as Mitchell Weiser headed in from another Diaby cross and Kerem Demirbay chipped over the goalkeeper.

The Bremen city government had been sceptical about hosting soccer games, though it joined other German states in letting them go ahead.

Mayor Andreas Bovenschulte said on Monday on TV channel ARD that it was a "very problematic signal to society" to allow football at a time when other people in Germany were encouraged to follow social distancing.
