The German Olympic Sports Confederation (DOSB) has raised concerns about a supposed €42 billion (£32.8 billion/$45.7 billion) backlog in the reconstruction and modernisation of sports venues in the country.

Walter Schneeloch, the DOSB’s vice-president of sport development, has demanded a "Nationale Allianz Sportraumentwicklung" - National Alliance sport spatial development - with the aim to invest more in the public use of sports facilities.

Schneeloch has suggested a broad cooperation between the German Sports Ministers' Conference, the DOSB, the German Association of Cities, the German Federation of Municipal Authorities and other experts in a bid to resolve the problem. 

"Germany neglects its public use infrastructure," Schneeloch said.

"We drive our sports facilities to wear.

"We recognise the diverse public funding initiatives by states and municipalities, although they are far from sufficient."

The DOSB has also committed to a programme supporting the Federal Government in the rehabilitation of some 1,000 sports halls currently being used nationwide for refugee accommodation.

International Olympic Committee (IOC) President Thomas Bach claimed in November that Germany's ongoing refugee crisis contributed to Hamburg's citizens voting against the city bidding for the 2024 Olympics and Paralympics.

Hamburg dropped out of the race following a 51.6 per cent vote against the €11.2 billion (£8.7 billion/$12.2 billion) project in a public referendum.

The result, which left just four cities - Budapest, Los Angeles, Paris and Rome - in the running dealt a heavy blow to the Olympic Movement, which had hoped that the German poll would snap a losing streak that has seen a long line of cities, including Munich, turn their backs in one way or another on the chance of hosting an Olympic Games.

Germany has not hosted an Olympics since Munich 1972.

A bid from the same city for the 2022 Winter Games was dropped after citizens against it in a referendum in 2013. 

The host of the 2024 Olympics is due to be chosen at the IOC Session in Lima in September 2017.
