The fullback is impressing on-loan with Schalke this term.
Brands wrote for the club's accounts report: “He was ready to play but we had Seamus Coleman playing regularly in that position.
“We needed to give Jonjoe, at this stage of his career, the opportunity to play regular football at a very good level. But we also needed two players in the right-back position.
“Schalke in Germany was a perfect loan move for Jonjoe and he is now playing every week.
“We are sure he will come back to compete in the first-team next season."
