After joining in September 2000 Vignal finally got an extended run in the side
in the beginning of the 2001/02 season. Markus Babbel had contracted Guillan-Barre syndrome and Jamie Carragher was moved to the right flank allowing Vignal to slot in on the left. The Frenchman linked up well with John Arne Riise in front of him and showed some attacking prowess. Unfortunately, Vignal fractured his foot when Liverpool got dumped out of the League Cup by Grimsby on 9 October 2001 and was out for the rest of the campaign. He made four appearances for the side in the 2002/03 season, but Vignal was clearly far away from being match fit. He was loaned to Bastia in his native France and was again loaned out in the 2003/04 season, first to Rennes in France, next to Espanyol in Spain and then to Rangers in Scotland. He eventually joined Portsmouth after he was released from his Liverpool contract a year early in the summer of 2005.
Vignal actually made more League appearances for Portsmouth, 14, in the 2005/06 season than he had made in the whole of his Liverpool career, 11. However, he left Portsmouth on a free transfer in the summer of 2006 and again returned to France, this time to represent Lens. But Lens then loaned him out to German club Kaiserslautern for the second half of the 2006/07 season. In July 2007 the 26-year-old was again to be found in English football, this time on loan at Southampton that attempted unsuccessfully to return to the Premier League. Vignal appeared in 20 of their matches in the Championship in 2007/08, scoring three goals, all penalties. In 2009 Vignal joined Birmingham City, but Injury restricted him to just eight Premier League appearances in the 2009/10 season, at the end of which the Midlands club decided not to take up the option of an additional year on his contract. Still just the right side of thirty, the defender looked for another British employer and in July 2010 had trials with two Championship clubs, Cardiff City and Sheffield United. Ultimately neither of those trials led to an offer of employment. In September 2010 Vignal moved to Atromitos in Greece on a one-year contract but only played in four Greek Super League fixtures. After a season without a club, Vignal joined Dundee United in September 2012.
Vignal left Dundee United in November 2012 without playing in a first-team match for them. He made the match-day squad for three Scottish Premier League matches but was not called on in any of those fixtures. His Dundee contract officially lasted until January 2013 but the defender was still without another club as the 2012/13 season ended and his thirty-second birthday approached. Vignal returned to the country of his birth after his unsuccessful time in Scotland and during the summer of 2013 signed a contract with Avenir Sportif Béziers, a club that plays in the fourth tier of French football. After retiring from playing at the end of that season he took over the presidency of amateur club CEP Palavas and in January 2018 was appointed an academy coach at Rangers.
