Just looked it up, given my own wonderings about the end of his contract, I didn't realise he signed a new 5 year one in 2016 (ends 2022). £350,000, not Euros....after taxes.

Seems doubtful. Unless he really wants out due to concerns about game time.
That was a mistake. He'll suddenly be their lowest paid player after Brexit.
