Le Havre director general Arnaud Tanguy told L'Equipe that it wanted to wait to find a
replacement for Thierry Goudet, fired at the end of September, and was surprised when Bradley's resume crossed his desk.
Bradley, who has been joined by former U.S. national team trainer Pierre Barrieu, has been at Le Havre for less than a week, but HAC players said they have already noticed a change.
"We've felt a change in practice with some very intense training sessions," midfielder Alexandre Bonnet told L'Equipe. Forward Mathieu Duhamel described practice as "intense but very varied."
Le Havre's goal is to return to Ligue 1. It was last relegated in 2009 and since then finished no higher than sixth in the 20-team Ligue 2. It was seventh in 2015.
Le Havre's inability to be a consistent contender is in contrast to its reputation for producing talent. Ibrahim Ba, Jean-Alain Boumsong, Lassana Diarra, Vikash Dhorasoo, Charles N'Zogbia and Paul Pogba have all gone to be French internationals. Diarra and Pogba started in France's 2-0 win over Germany played as the Paris attacks began outside the Stade de France.
Le Havre plays in one of the newest stadiums in France. The Stade Oceane, opened in 2012, seats more than 25,000 fans. A crowd of 5,965 fans turned out on Monday night for the game against Brest.
American businessman Vincent Volpe, who has worked in Le Havre for 25 years, bought a majority interest in Le Havre earlier in the year and plans to invest $11 million in the club with the goal of winning promotion this year or next.
Bradley will get his first test of how viable Le Havre's chances of winning promotion this season are on Saturday when it travels to face first-place Nancy on Saturday.
