The Bundesliga club's director of sport, Max Eberl, says that the Germany international will not stay - even if a proposed move to Camp Nou collapses
The Germany international has agreed to move to Camp Nou at the end of the season but the deal has been thrown into jeopardy by Fifa's decision to ban the Blaugrana from signing any players for the next two transfer windows in relation to alleged irregularities in the movement of players under the age of 18.
That shock development has thrown up the possibility of Ter Stegen remaining at Gladbach for the final year of his contract with the club but director of sport Max Eberl says the 21-year-old will still depart, pointing out that they have already signed a replacement in the form of Basel's Yann Sommer.
"I think you can see from how relaxed we are sitting here that our situation has not changed," Eberl told reporters on Friday.
"Marc will leave us in the summer and we will then have Sommer as our new goalkeeper.
"I cannot envisage any scenario that could arise that would mean he would be staying with us."
Ter Stegen, for his part, has also stated that he fully intends to leave Monchengladbach this summer no matter what.
