Barcelona technical director Andoni Zubizarreta has refused to rule out the possibility of a move for Borussia Monchengladbach goalkeeper Marc-Andre ter Stegen, after insisting that the Catalan club's search for a new number one is ongoing, reports Sky Sports.
The 21-year-old Germany international is just one of a growing number of stoppers to have been linked with a transfer to Camp Nou next summer, as Gerardo Martino looks for a long-term successor for Victor Valdes.
Valdes will be out of contract at the end of the current campaign, and has made clear his intention to leave Spain, and take in a new challenge abroad.
Interest in Ter Stegen was believed to have cooled following reports from some Spanish media outlets suggesting that the Primera Division champions had turned their attention to alternative transfer targets.
However, after Zubizarreta's recent visit to Germany, speculation is rife once again that the Bundesliga custodian is being lined up by Barcelona.
"It is true that I was in Germany, because we are working on some subjects, but this operation is not closed," he told Canal Plus TV Spain.
"I recognise that many keepers are of interest, but it is not easy to find a man with the right characteristics to replace Victor Valdes.
"Barcelona never speak about chances for the squad, but we still have enough time until July 2014."
