The German goalkeeper has found greater confidence and regular playing opportunities in the Netherlands after a difficult period at the Camp Nou, but says it is too early to decide what happens when his loan expires.
Ter Stegen joined Ajax last summer after 12 years at Barcelona, where his position had become increasingly uncertain. His relationship with head coach Hansi Flick had deteriorated, and the goalkeeper eventually moved to Amsterdam in search of regular football.
The 34-year-old remains under contract with Barcelona until June 2028, meaning a return is still possible when his loan ends. Asked about his future in an interview with Sport Bild, he made clear that he has not closed the door on the Catalan club.
"I played at Barcelona for 12 years and, therefore, naturally have a close relationship with this club. We are only in November, so I really cannot say what will happen in the summer," he said.
Barcelona are understood to view the current loan as a possible step towards a permanent separation, particularly given the goalkeeping options available to Flick. Joan García and Dominik Livaković are among the alternatives, making it difficult to see how Ter Stegen could immediately reclaim a regular starting position.
The goalkeeper's comments nevertheless suggest that his personal connection with Barcelona remains strong. He has not indicated that he wants to terminate his contract or force a permanent departure, preferring to leave his options open until the end of the season.
A return would also raise questions about his prospects with Germany. Ter Stegen has regained an important role with the national team under head coach Jürgen Klopp, and regular football has helped restore his confidence.
He welcomed the trust shown in him by the Germany coach, explaining that it had reinforced his belief in his ability to contribute at the highest level.
"It feels extraordinarily good to have that confidence placed in me. It shows that, when I am fit, I can bring a lot to the team," he said.
His immediate priority is to maintain that form at Ajax and with Germany. Returning to Barcelona without playing regularly could jeopardise the momentum he has rebuilt, especially with international competition ahead.
Ter Stegen also revealed that he has not recently been in contact with Flick, although that does not necessarily mean a return to Barcelona is impossible. His future will depend on several factors, including the goalkeeper hierarchy at the Spanish club and the opportunities available elsewhere.
For now, the German is keeping his options open. His 12-year association with Barcelona remains important to him, but he is not prepared to make a commitment about next summer while the season is still underway.
