"We concede too many goals, this season and also last season, we have to improve that for next season," Witzel told WAZ after Saturday's 3-4 defeat against Bochum.
"I said 'we', but I won't be there at all, I'll be gone next season," he added.
"I am very happy that I have played here for four years at the highest level. But I am sad to leave the club, I have many friends and great teammates here," Witsel continued.
The 33-year-old has made 143 appearances for Dortmund, racking up 13 goals and six assists.
