Manchester United boss Erik ten Hag has moved to quickly resolve issues from previous reigns.
The Dutchman has overseen a remarkable improvement at United since arriving in the summer.
On the back of winning his first trophy, the Carabao Cup, pundits noticed how Ten Hag took care of a few issues pointed out by his present assistant Steve McClaren.
"[Anthony] Martial is not a No 9, he is not a striker," McClaren told Sky Sports a few years ago.
"All his goals, all his best moments are on that left-hand side.
Whether that's outside left or whether that's inside left, that's where he plays.
He cannot play down the middle on his own."
He added on Brazilian midfielder Fred: "Fred is getting better, more confident, but he likes to roam around. They've got nobody like a [Roy] Keane sat in there.
"Absolutely [Scott McTominay] could do that but he still goes and wanders, but at least he's got the physicality to get around. So they're missing somebody in there."
