Gabriel Sibley "Sid" Kimpton, also known as George Kimpton, (12 August 1887[2] – 15 February 1968) was an English football player, who spent his entire playing career with Southampton and subsequently became a manager in Europe coaching DFC Prague, Polonia Warsaw, Cracovia[3][4] Le Havre, Coventry City, France national team,[5] RC Paris, Rouen[6] and Cherbourg.

He joined Southern League Southampton in September 1910; after one match for the reserves,[1] he made his first-team debut on 22 October, taking over the centre-forward's role from Percy Prince, in a 3–0 defeat by Crystal Palace.

[8] According to Holley & Chalk, Kimpton's "main value was his reliability and versatility"; he was "never thought of as a great player (but) had plenty of pluck and bustle which made him hugely popular.

"[1] For the 1911–12 season, Southampton's new manager George Swift recruited eleven new players, including centre-forward Henry Hamilton from Huddersfield Town.

Kimpton retained his place in the side, but moved back to right-half where he played for the first half of the season, before being replaced by John Denby in December.

Kimpton returned to the side in March, when he took over the outside-right berth from Jack Wilcox for the rest of the season, at the end of which Southampton were once again just above the relegation zone.

As the managerial team tried to improve performances by recruiting new players, Kimpton managed to retain his place in the side, either at centre-forward or on the right-wing, until February when he was dropped.

"[18] Before the World Cup match France-Austria played on 27 May 1934 in Torino, Kimpton asked French midfielder Georges Verriest to do a very tight individual marking on Austrian striker Matthias Sindelar.

Alongside his lessons, he became the manager of RC Paris and again brought the WM formation with sport director of les Pingouins, Victor Mestre.

[15] After the defeat of the France national team 3–1 versus Germany on 17 March 1935, the FFFA called up Kimpton to an assistant position to teach WM to French international footballers.
