Ben Mee, a central defender, was a free transfer when he joined the Bees.
He signed a two-year deal with the Bees after 11 years with the Clarets.
Thomas Frank said he was happy that they had signed Ben.
He will be a great addition to the squad. For six years, he was a good player in the premier league.
After the club's promotion to the Championship, he left for the first time in three years.
He joined the Clarets on a season long loan from Manchester City in 2011.
As a result of being demoted, Mike Jackson was assisted by Mee last season.
Frank said he loved his defensive mindset. He knows how to win fights, he knows how to block shots and he knows how to defend himself.
Leadership and communication is something he will bring to the team.
He has a good left foot, which will help us on set pieces. He is going to be added to the squad.
The signing of Albania goalkeeper Thomas Strakosha on a free transfer came just a few days after the loss of Christian Eriksen to Manchester United.
The Bees have signed a number of players.
