Jean-Alain Boumsong-Somkong (born December 14, 1979, in Douala) is a professional football defender who currently plays for Panathinaikos and the French national team.

Boumsong started his career with French team Le Havre before joining Auxerre. He notably scored the 89th-minute winning goal in Auxerre's 2–1 win in the 2003 French Cup Final against Paris Saint-Germain.

A long time target for then Liverpool F.C. manager Gérard Houllier, the press speculated that it was only a matter of time before Boumsong signed for Liverpool.[citation needed] However, as Boumsong was a free agent, his agent, the Monaco based Scot Willie McKay negotiated the best sign-on fee to the player for Boumsong from Rangers, based in Glasgow, Scotland.[citation needed]

As a result, Boumsong joined Alex McLeish at Rangers in 2004 and signed a five year contract. Boumsong quickly adapted to the Scottish game and showed his skill as a centre half, leading to rumours that his stay in Glasgow may be shorter than expected. Halfway through the 2004–05 season, Newcastle under new manager Graeme Souness, made an £8 million bid for him, which Rangers accepted in a deal that was finalized once the January 2005 transfer window opened.

Boumsong signed a 5½-year contract with the Magpies. However, as Boumsong had played the requisite number of games for Rangers that season, he still received a Scottish Championship Winners Medal, despite having been a Newcastle player for around five months by the time Rangers won the title.

The £8 million transfer fee raised eyebrows, as the player, being out of contract, had joined Rangers for free just months before- at which point Newcastle showed no interest in signing him. This transfer is one of those about which the Stevens inquiry report in June 2007 expressed concerns:

“There remains inconsistencies in evidence provided by Graeme Souness – a former manager of the club – and Freddy Shepherd – apparently acting in an undefined role but not as a club official – as to their respective roles in transfer negotiations.”

“The inquiry is still awaiting clarification from agent Willie McKay”.

However the Stevens enquiry later issued two clarifications. It said of Souness, "We wish to make it clear that inconsistencies did not exist within the evidence given by Graeme Souness to Quest concerning his role in transfers covered by the Inquiry during his time as manager of Newcastle United FC and neither the Premier League nor do Quest have any concerns in this regard". As regards McKay it stated: "Further to the key findings from the final Quest report published on 15 June 2007 by the Premier League, Quest would like to emphasise that, in that report, it was clear that no evidence of irregular payments was found in the transfers in the inquiry period which involved the agent Willie McKay. Quest would also like to thank Mr McKay for his cooperation with the inquiry."

He had a mixed time during his stay on Tyneside in regards to his form. During his first season at Newcastle he was praised for his defensive abilities and partnership with Titus Bramble. His popularity led to fans shouting the first syllable of his name, elongating the sound in a similar way to Arsenal fans chanting Nwankwo Kanu's name.
