In March 2004 after injuries to Carlo Cudicini and Neil Sullivan,[4] Ma-Kalambay found himself on the bench for a league match at Bolton Wanderers as cover for Marco Ambrosio.

On 18 October, Ma-Kalambay made the bench for Chelsea's 1–0 Champions League group stage win against Barcelona, due to injuries to Petr Čech and Carlo Cudicini.

In a 2020 interview, Ma-Kalambay revealed that he was hurt and taken aback by the level of racist abuse he received from the Hearts support on his debut, describing it as the worst he experienced throughout his career.

Ma-Kalambay has received some criticism at times for his performances for Hibs, but he claimed during an interview with the Daily Record in December 2008 that he is under greater scrutiny than goalkeepers of other Scottish Premier League clubs.

[10] The newspaper surmised that this scrutiny was because of the high-profile mistakes made by his immediate predecessors in the Hibs goal, Zbigniew Małkowski and Simon Brown.

[12] Hibs signed goalkeeper Graeme Smith on the first day of the January 2010 transfer window, however, which raised further doubt over Ma-Kalambay's future at the club.

In August 2013, Ma-Kalambay signed a contract for two seasons with Belgacom League club Royal Antwerp after a few weeks training in the preseason.

[26] Belgium eventually finished in fourth place; Ma-Kalambay missed out on a medal due to Belgian defeats by Nigeria and Brazil.
