Nelson played in goal for Orient in the 2007-08 season, making 33 appearances with 30 coming in the league. He continued his career at Norwich, Aberdeen and Notts County before ending up at Gillingham last season where he was the undisputed first choice last season, making 48 appearances, including getting sent off against Accrington Stanley with a straight red card.
The 31-year-old won the League 2 title last year with Gillingham and must be hopeful of keeping his spot between the sticks for the new campaign.
Frampton made his solitary appearance for the O’s in the 2010-11 season, whilst on loan from Millwall. After finishing loan spells with the O’s and Swindon Town respectively, he moved to Gillingham in 2011 where he has since played 66 times.
Despite his limited playing time for Orient, the former Millwall player of the season played most games for the Gills and like Nelson formed the spine of the Gillingham team that went on to win the league. Frampton is out of contract but has been offered a new deal with the club.
The last of the Gillingham trio, Barrett probably has the closest ties with the O’s of the three having come through the youth system in E10. After spells at Plymouth, Bristol Rovers and Southend United among others, he re-joined the O’s on loan from Crystal Palace in March 2011, with a short-term loan until the end of May, making 14 appearances.
After the loan spell, he moved to Bournemouth and finally Gillingham and was ever-present in their back four, with 46 appearances and a goal against Plymouth.
The Rotherham forward had a great season for the O’s back in 2010-11, where he scored 16 goals and led the O’s front line as they finished just short of the play-offs and enjoyed success in the FA Cup.
After moving north, the goals have dried up to an extent, with only 17 goals in 89 appearances altogether yet ‘Revs’ is still a key component of the side which finished second in the table behind the Gills and picked up the player of the year award. He also has a habit of scoring against his former sides so the O’s will need to be on their toes next season.
Zakuani is a former trainee at the club who broke through and played a key part in the promotion season of 2005-06. He left in 2006 for a reported £1,000,000 fee, joining Chris Coleman’s Fulham side, where he was unable to break into the first team making only two appearances in three years, none of which came in the league.
He bounced back, with loan moves to Stoke and Peterborough but finally settled on the Posh and agreed terms in the 2008-09.
He has made 147 appearances for the Cambridgeshire club though it remains to be seen whether he will be lining up against the O’s next season after he rejected a contract extension at London Road and has been transfer-listed.
