In a message on the Argyle website, chairman Simon Hallett said the club were “disappointed” in the “timing and manner” of Muslic’s departure.

“After the season ended, and with rumours flying that Miron was attracting interest from other clubs, I called him personally and he assured me that he was 100% committed to Argyle. His colleagues had no indication that he wanted to leave,” he said.

“Last Saturday, Miron informed the club that he wished to speak with Schalke with a view to joining them. Under his contract, a club wishing to speak with him needs Argyle’s prior permission. We were unwilling to give such permission, but Miron informed us that under no circumstances was he going to return to Plymouth. Thus, we reluctantly gave the necessary permission.

“By making clear his intention never to return, Miron gave us no choice but to move on. We could have insisted on the full compensation and gone to court to enforce his contract but would not have had his services as head coach, and progress on recruiting a replacement would have been blocked.

“Rather than get mired in a protracted, and highly disruptive, process we settled for an amount of compensation that, while below the contracted sum, is a strong financial outcome for a League One head coach, enabling us to move on positively.”
