de Jong will return to Barcelona between Monday and Tuesday to undergo further tests on his knee injury, with surgery not ruled out, according to Barca Universal.
Analysis:de Jong could be sidelined for around four months if the worst case diagnosis is confirmed, a significant blow that would leave Barcelona without one of its key midfielders for a large chunk of the new season. The upcoming tests should provide more clarity on the severity of the issue, and further updates on his status and potential surgery are expected next week. Marc Bernal could therefore stay at the club and see increased playing time in his spot.
