One of Manchester United’s new shirts is among several made from waste plastic recovered from the sea.

Adidas developed the shirt in partnership with Parley, a campaign group working to stop waste plastic getting into the oceans.

It has also developed such shirts for European champions Real Madrid, German champions Bayern Munich and Italian champions Juventus.

United’s navy blue top is quite striking but rather more fetching is the third strip of Real Madrid, which was designed in coral pink to highlight the damage being done to coral reefs.

Rival sportswear giant Nike is involved in a similar project: it has made shirts from waste plastic for Barcelona and the Australia, South Korea and Saudi Arabia national teams.

Nike says a minimum of 12 recycled plastic bottles are used in the manufacture of its football shirts.

According to Greenpeace, 12.7 million tonnes of plastic are dumped in the ocean every year.

Meanwhile Chelsea FC’s new third kit is the first in the world to be connected to the internet.
