England's bid to host the semi-finals and final of Euro 2020 at Wembley could be unopposed, with Munich thought to be considering dropping its rival bid.
The German football association (DFB) may only bid for Munich to host group games in order to strengthen Germany's bid to host Euro 2024.
"Our decision is open," said DFB president Wolfgang Niersbach.
"We have an excellent relationship with the FA and we are thinking about how we can support the other association."
Uefa's executive committee will vote on the host cities for the 2020 tournament on 19 September.
Niersbach confirmed that Germany would bid for Euro 2024, with Turkey likely to be the country's main opponent for the staging of that tournament.
