I didn't see the match but he's been their less than a month; too little time to have properly assessed the squad and got the ones he didn't fancy out and enough of his own players in. Also too little time to have got the players fit through pre-season in his own way. And that's without even mentioning the time it takes to get the players to understand and buy into your way of doing things. On top of all that it seems he doesn't really have much money to spend relative to the clubs around about him.
If the fans are booing him at this point then I think they're out of order. Just more of the same with football at the moment. Might even get sacked if he loses a couple more games! 😆
