Freiburg defender Fallou Diagne is reportedly on the verge of joining Borussia Dortmund, reports France Football.
The Millionaires are actively searching for defensive reinforcements seeing as how Felipe Santana looks likely to leave in the summer.
Jurgen Klopp has looked at a number of players over the last couple of months, but it appears he has decided to make a move on the Senegalese stopper.
The player who has a contract until June 2016 should be available for mere €4 million in the summer and it is no secret Borussia will have money to spend in the upcoming transfer window.
The Millionaires have already established first contact with Freiburg and they are expected to close the deal in the next few weeks.
Fallou Diagne, 23, joined Freiburg from Metz in January 2012 and has since clocked up 45 Bundesliga appearances, scoring 2 goals in the process.
