Adidas have launched a limited edition Manchester United trainer called the 'Stretford'. Picked up very quickly by United fans, however, is the fact that the trainer is in the sky blue colour of fierce local rivals Manchester City.

This led to many a United questioning Adidas's decision on Twiter.

Upon replying to a bombardment of questions from irate United fans on the colour, Adidas said that the blue represents the colour United wore during their 1968 European Cup final success over Benfica at Wembley Stadium, when they defeated the Portuguese side 4-1.

United face City in a crucial Premier League derby next Sunday. Just how many pairs of 'Stretford's' that will be worn remains to be seen.
