Paul Scholes' resignation was made via WhatsApp

Scholes is also understood to have not spoken to any members of the Oldham board of directors since sending the message. Club chairman Abdallah Lemsagam has spoken out on his disappointment about Scholes' resignation.

"Oldham Athletic are disappointed by Paul's decision to resign and surprised by the reasons he has given," he said.

"The club gave Paul all the support and autonomy that he asked for. He did not raise his concerns at all, informally or formally, prior to his resignation. He gave no opportunity to address any issues at all, simply resigning by text and then refusing to discuss matters.

"Management is a difficult job and we would have worked with Paul to find solutions, had we been given the chance. We wish him well and thank him for his contribution. We will start the search for a new manager immediately."
