Borussia Dortmund is about to return from Bayern-Munich defender Mats Hummels to Westfalenstadion.
The 30-year-old is expected to return to his former club worth £ 22m after winning the Reds three consecutive titles.
Talks between the two clubs are at an advanced stage after initial contacts were made this week.
Hummels came through the ranks at Bayern, where his father was youth coach before he was loaned in 2008 under Jürgen Klopp to Dortmund.
The following year he finished a permanent change for only 4 million pounds, won two Bundesliga crowns at Signal Iduna Park and reached the Champions League final in 2013.
The World Champion returned to Bayern in 2016 with a transfer of £ 30m, but his place under Niko Kovac is anything but safe.
Hummels started in only 20 league games last season, and his place is expected to be taken by French defender Lucas Hernandez in the starting eleven. He signed at Atletico Madrid for 72 million pounds.
Although Hernandez is his first choice for left-back for his country, he is in the heart of the Bavarian defense, with David Alaba remaining the first choice for left-back.
Therefore, Bayern are ready to bet on Hummels, who was released by Jogi Loew at the beginning of the year from the squad of Germany, and Kovac is pleased to win a player who will be 31 in December.
A return for Hummels was already expressed in April to the CEO Hans-Joachim Watzke, when he appeared on Sky TV in Germany.
At that time Watzke seemed to reject a possible return and declared: "I believe that Mats will stay with Bayern Munich, I am sure of that I am convinced.
"We have four center-backs for the new season and still (Leonardo) Balerdi.
"[But] Basically you should never exclude anything in football, I have learned over the years, but you can forget the topic. "
Dortmund drove the title race to the last day in 2018-19, but Lucien Favre wants to add more experience to a young and somewhat fragile defense.
It is unlikely that Hummels is the only experienced man to leave Bayern. Jerome Boateng was asked by President Uli Hoeneß to seek a new club.
