Keeper could leave Middlesbrough permanently in the summer transfer window

Dejan Stojanović signed for Bundesliga 2 side St. Pauli on loan in the winter transfer window, and he could be set to join them permanently.

According to reports, St. Pauli are interested in signing Middlesbrough goalkeeper Dejan Stojanovic on a permanent deal. However, his transfer fee could block them from permanently signing the 27-year-old.

Stojanović signed for the Bundesliga 2 side on loan in the January transfer window after finding it difficult to get regular playing time in Neil Warnock's team.

He has made 14 appearances for the German side, keeping four clean sheets.

St. Pauli want him to stay after impressing, but it is subject to Middlesbrough's decision.

St. Pauli sporting director Andreas Bornemann said "Dejan is doing a really good job and has become an important pillar for the team."

"He feels comfortable here and would like to stay. Of course, it’s an option that Dejan will also be between the posts with us next season. A lot depends on how Middlesbrough plan with him and imagine a possible transfer financially."

St. Pauli will reportedly be unable to pay as much as 500,000 Euros, a fee that is less than half the amount Boro paid for Stojanovic.
