Vignal then played in a friendly match against Sporting Gijón as part of a trial with Birmingham City, newly promoted to the Premier League. After producing what manager Alex McLeish described as a "strong performance", Vignal signed a one-year contract with the club, with an option for a further year, subject to medical examination. Injury disrupted his season, which combined with the form of Liam Ridgewell at left-back restricted the player to just nine first-team appearances. The club chose not to take up the option of a second year.
