Manchester United badge in the 1960
The club crest is derived from the Manchester City Council coat of arms, although all that remains of it on the current crest is the ship in full sail.The devil stems from the club’s nickname “The Red Devils”; it was included on club programmes and scarves in the 1960s, and incorporated into the club crest in 1970, although the crest was not included on the chest of the shirt until 1971 (unless the team was playing in a Cup Final).
A photograph of the Newton Heath team, taken in 1892, is believed to show the players wearing a red-and-white quartered jerseys and blue shorts.Between 1894–96, the players wore distinctive green and gold jerseys which were replaced in 1896 by white shirts, which were worn with blue shorts. After its name change in 1902, the club colours were changed to red shirts, white shorts, and black socks, which has become the standard Manchester United home kit. Very few changes were made to the kit until 1922 when the club adopted white shirts bearing a deep red “V” around the neck, similar to the shirt worn in the 1909 FA Cup Final. They would remain part of their home kits until 1927.In 1934, players sported cherry and white hooped shirts, but the following season the red shirt was recalled after the club’s lowest ever league placing of 20th in the Second Division.The black socks were changed to white from 1959 to 1965, where they were replaced with red socks up until 1971, when the club reverted to black. The current home kit is a red shirt with a white collar, worn with white shorts and black socks.
The Manchester United away strip has more often than not been a white shirt, black shorts and white socks, but there have been several exceptions. These include the navy blue shirt with silver horizontal pinstripes worn during the 1999–2000 season, and the current away kit, which has a royal blue body and sleeves with hoops made of small midnight navy blue and black stripes, with black shorts and socks. An all-grey away kit worn during the 1995–96 season was dropped after just two games because players claimed to have trouble finding their team-mates against the crowd. In 2001, to celebrate 100 years as “Manchester United”, a reversible white/gold away kit was released, although the actual match day shirts were not reversible.
The club’s third kit is often all-blue, this was most recently the case during the 2008–09 season, to celebrate 40 years since it was worn for the club’s first European Cup win in 1968. Exceptions include blue-and-white striped shirts worn during the 1994–96 season, an all black kit worn during the Treble winning season, and white shirts with black-and-red horizontal pinstripes worn between 2003–05.
