My advice to him is to save his money wisely for re-training into a new career once his contract is up next summer. Last night has hammered home within the football world about how dreadful he is, it’s far from just Saints. His spell in Belgium was dreadful as well.
He might get a financial disaster EFL club but otherwise he’ll be out of the professional game at any level by 26/27 yo. He’s got enough money to start a business/learn a trade or do a degree so he has options.
