Lucas Digne was signed by Villa in a deal worth up to £25m.
Villa beat off interest from several other teams, including West Ham, to join the club.
Following the arrival of Philippe Coutinho, Steven Gerrard brought in his second signing as manager, with Yves Bissouma also a target.
When Lucas became available, we jumped at the chance to bring him to the club.
"Signing a player of his quality and experience in the January window is a great addition to our squad and his arrival excited me and everyone associated with Villa."

Pete Smith of Sky Sports explains what Lucas Digne would bring to Villa.
Digne moved to Villa because of his friend and former teammate, Gerrard.
Digne said he came for the manager.
I had a good meeting with him, and we spoke a couple of times during the month. I feel his desire to win to show his football as a manager.
The second signing of the January transfer window is Lucas Digne.
I feel like it's what I want to show the fans.
Digne told the club he wanted to leave Goodison Park this month after falling out with the manager.

After the Spaniard made public his desire to leave last week, Digne appeared to take a shot at him in a farewell post.
Digne and Benitez are no longer at the club.
Digne wrote that everything must come to an end. I didn't think it would end this way. I am sad because of what has happened and some things that were said about me.
"Wherever I go, I will always carry you with me."
It only takes one person to destroy a love affair.
Digne was the top chance creator last season.
Sky Sports News was told that Digne was wanted for 30 million dollars.
Vitaliy Mykolenko is a replacement for Everton. In the January window, the Toffees secured the services of Rangers and Scotland right-back Nathan Patterson in a deal worth £16m.
Digne has played in 15 games and scored once for the 15th-ranked club, who will be looking to improve on their 15th place position when they travel to Norfolk on Saturday.
