[4][5] Makofo gained something of a cult following during his time with MK Dons thanks to the computer game Championship Manager 4, in which the youngster was one of the 'must sign' players.
[14] Makofo signed for Grays Athletic on 26 June 2009, along with Marcel McKie, Nick McKoy and Allan McLeod.
[21] Following his performance during Kettering's win over York City in October, player-coach Paul Furlong commented that "Gareth Bale is the same sort of player as Serge.
Manager Neil Woods was dismissed early on into Makofo's Town career, and on 18 April 2011 the player was told he had no future at the club by the new managerial duo of Rob Scott and Paul Hurst.
[23] Grimsby chairman John Fenty said on 16 May that the signing of Makofo had been a "disaster",[24] and that he had recently been on trial with Lincoln City after being told he was surplus to requirements.
[25] Makofo was given an opportunity to regain a first team place in the summer of 2011, and his pre-season performances earned him a place back in the squad, but after suffering a foot injury in mid season, Makofo struggled to break back into the team and saw out the 2011–12 season struggling to break on to the substitute bench.
On 12 May 2012, and for the second season running Makofo was told by Scott and Hurst that he was not in the management duo's plans, with this Grimsby began to work on a settlement agreement with the player to terminate his contract.
[27] On 14 July 2012, he joined Ebbsfleet United on trial and came off the bench to score in a 6–1 away win in a friendly fixture with Tonbridge Angels.
[28] He also played in Fleet's friendly with Leyton Orient but was released along with fellow trialists Ashley Winn and Kirk Hudson.
