Clubs had to name a line-up of players who are OVER 21 and at least eight of them had to be homegrown.
A homegrown player is one who has been registered with an English or Welsh club for three years before they are 21.
Managers can use as many under 21 players as they want, regardless of nationality.
A home-grown player means one who, irrespective of his nationality or age, has been registered with any club affiliated to the Football Association or the Football Association of Wales for a period, continuous or not, of three entire seasons or 36 months prior to his 21st birthday (or the end of the season during which he turns 21).
Players under the age of 21 (for the 2011/12 campaign those born on or after January 1, 1990) are eligible over and above the limit of 25 players, which explains why the likes of Mario Balotelli are not listed at Manchester City even though he is a part of the first-team.
Everton named just 18 players - seven short of the maximum - in their official squad and - despite much speculation - Wayne Bridge, the out-of-favour left-back, was selected in Manchester City's squad of 24.

Missing in action: Playing for Belgium will be the only European action for Chelsea's Romelu Lukaku this season
Andre Villas-Boas has left £20million striker Romelu Lukaku out of Chelsea's Champions League squad.
Lukaku, 18, has been sacrificed by Villas-Boas because Chelsea did not have enough 'homegrown' players to maximise their 25-man squad.
Michael Essien has also been omitted because of his long-term knee injury and so has Ryan Bertrand, an English victim of spending so long on loan at different clubs.
Chelsea have only been able to name 22 players on their 'A List' for the Champions League because they only have John Terry who qualifies as one of four allotted 'club trained' places.
It is a problem every year. Last year, Paulo Ferreira missed out but since the sale of Yury Zhirkov and failure to sign Alvaro Pereira from Porto Ferriera will be needed as potential cover at left-back.
Frank Lampard, Daniel Sturridge, Ross Turnbull and Ashley Cole make up the four 'association trained' places. Teenagers Josh McEachran and Nathaniel Chalobah can both play because they qualify on the 'B List'.
Bertrand's omission makes a mockery of the homegrown rule. He is English born but fails to meet the criteria because he was not registered at Chelsea for three years between the ages of 15 and 21.
Chelsea's new signing Romelu Lukaku has been omitted from their 22-man Champions League squad.
With only 17 non-homegrown players allowed by UEFA regulations, the 18-year-old striker, who cost a reported £20million from Anderlecht, will not be able to feature in the group stages.
Given only four of the eight homegrown players can be "association trained", England under-21 international left-back Ryan Bertrand is another not included.
However, promising young midfielder Josh McEachran will be available as the 18-year-old is set to be part of Chelsea's 'B' list.
Chelsea's other summer signings Oriol Romeu, Juan Mata and Raul Meireles are all in the 22-man group.
Regulations for the domestic Premier League are different, and would see Lukaku counted as one of Chelsea's under-21 players, so not part of the 25-man quota.

essien kena omitted

Hargreaves joined Manchester City this week and immediately targeted the group-stage tie with his old club.
But the midfielder's hopes have been squashed after he was left out of City's Champions League squad.
He may yet play in the tournament though, as Roberto Mancini can review the 25-man list in January.
Wayne Bridge also missed out although there is a spot for Kolo Toure, who has served his six-month drug ban.
