Liverpool reportedly want to sign ter Stegen in January.
Liverpool boss Jurgen Klopp has only been in charge at Anfield since last month, but a report in Catalan media outlet Sport claims that he has already started planning a move for his first January signing.
The German boss has identified that signing a new goalkeeper is a necessity to make Liverpool a competitive team again, and Klopp has outlined who he wants to replace Simon Mignolet between the posts.
Klopp wanted to sign ter Stegen from Borussia Monchengladbach, but he decided to move to Barcelona instead.
Commonly regarded as the best young goalkeeper in world football, ter Stegen already has four caps for Germany, and is seen as the long-term replacement for Manuel Neuer in the German ranks.
However, the report claims that the youngster is somewhat unhappy at Barcelona, as he is still not first choice keeper. Despite being the cup and Champions League keeper - and leading Barca to Champions League success last season - Claudio Bravo still takes part in La Liga action.
Ter Stegen wants to be playing more, and whilst the report claims that he is not yet looking for an exit, the keeper could change his stance if a good opportunity arises.
Liverpool could be this team, with ter Stegen undoubtedly good enough to be first-choice at Anfield, and if an offer is submitted by the Reds, the keeper may just consider his options.
