The Bundesliga championship shield has been expanded again in time for Bayern Munich to potentially wrap up another title on Sunday.

The German Football League (DFL) said on Wednesday that the outer ring was replaced by a larger one which will allow the champions to be engraved for the next 30 years.

The silver and gold shield now has a diameter of 56 centimetres and weighs more than 11 kilograms.

The DFL said the trophy was designed and crafted in 1949 by art professor Elisabeth Treskow at the Cologne School of Arts and Crafts, replacing the Victoria statue, which went missing during World War II.

It has the names of all German champions since 1903 engraved and has been enlarged twice, in 1981 and 2009.

In the latest move, the shield was completely disassembled and restored. The old outer ring was replaced by a new one which has two additional bands for the next champions.

Bayern can clinch a 35th German title, and 34th in the Bundesliga era, on the weekend with four games to spare if they earn one point more against VfB Stuttgart than rivals Borussia Dortmund at Hoffenheim.
