In 2006–07, he scored five goals in 35 matches, as Le Mans easily retained its Ligue 1 status (12th position), and was also linked with a move to Paris Saint-Germain as a replacement for departing Vikash Dhorasoo in the January transfer window – nothing came of it eventually; in his last season, he reunited at the Stade Léon-Bollée with compatriot Gervinho, a former teammate at Beveren.

On 21 May 2008, Romaric signed for Sevilla FC in Spain, penning a four-year contract for a fee believed to be around €8 and 10 million,[6] and linking up with countryman Arouna Koné.

He scored his first La Liga goal on 7 December, in a 4–3 away win against Real Madrid,[7] and finished his first season with 36 matches (30 starts), as the Andalusians were ranked in third position.

[9] On 26 July 2012, Romaric negotiated a release from Sevilla, and signed a two-year deal with fellow league team Real Zaragoza under his former manager Manolo Jiménez.

[10][11] He played only 14 total matches, as the Aragonese ended the season with relegation, and was sent off in the ninth minute of a 1–0 home loss to Getafe CF on 6 October for a foul on Mehdi Lacen.

[12] Romaric returned to France and its top flight on 1 August 2013, joining SC Bastia for two years with the option of a third and reuniting with his Le Mans boss Frédéric Hantz.

He scored his first international goal on 29 March 2009, opening 5–0 home win after just 28 seconds against Malawi for the 2010 World Cup qualifiers; the result was overshadowed by a crush that killed 19 spectators.
