HM Revenue and Customs have sought a bankruptcy order against the France international over a tax debt of nearly £800,000. During a high court hearing over the debt, Louis Doyle KC, representing Mendy, said: “He is embarrassed about the fact that he is not able to discharge it quicker than he is able to. He is saying ‘I want to pay as quickly as I can, I realise that I am in difficulty’.”
In a context where he's bankrupt so has nothing to lose, this makes more sense.
Surprised he found a lawyer willing to take it on, given their chances of getting paid, which suggests he has some probability of success.
Not sure how finances are really what should be embarrassing him, mind.
