What'll likely happen is, he will either get a huge payoff or run down his contact whilst every few months saying he is desperate to play.
Contract over he will hope a decent club signs him, say a Wolves or Southampton. Reality will kick in once he is signed on a free by Barnsley or Fleetwood. Once he finds a new lower division team his appetite for football will completely vanish and he will retire once his contract is mutually terminated.
He will always be known as a millionaire bellend like David Bentley and those type of players who could have had it all but instead threw it all away.
