Pontus Jansson has left Leeds United for Brentford.
The 28-year-old made 120 appearances for Leeds after joining from Torino in 2016.
Bees boss Thomas Frank told the club's official website: "We are very pleased with Pontus' arrival.
"The defence is an area that we have been looking to strengthen and we feel that Pontus will bring a lot to the group.
"Pontus is a top defender who brings immense professionalism, a great attitude, experience, defensive robustness, leadership qualities, and threat from set pieces to our side.
"Everyone knows about the Brentford model but to develop the young players we have here, we also need experience and quality in the squad to get the perfect balance.
"To have someone with his CV turn down other offers to join us shows where we stand as a club now."
