This isn't a mess of Sam's creation. It's Koeman/Walsh's. Give him the summer and the start of the next season to try and sort it out.
Mate, he's had 4 months and the style of play is shocking, if he was any kind of progressive manager he'd have an attacking style of play going by now.
He's use to firefighting, being hard to beat, scraping results to keep teams up, you do not associate Sam Allardyce with attacking pleasant on the eye football, he's not the one for us.
Served his purpose, we are in the Prem next season, give him his 6m and lets move on to a manager that can get us playing proper football fitting of this club.
