The 25-year-old claims that he had offers from a number of clubs in different countries, but Watford was the best option for him.
"I had other proposals, yes, even a German club. But I preferred to sign for Watford because this is a good club," he told 'L'Equipe'.
The right-back cited Watford boss Walter Mazzarri as one of the main reasons why he joined the club.
"I feel with him [Mazzarri] I can continue to progress," he added.
"He wants to play his 3-5-2 team, this is a system that suits me well because we played in a slightly similar way with Marcelo [Bielsa] at Marseille".
