There's pretty big space between disciplinarian and people-manager. Wayne understands footballers, gets close to them personally, and is upfront and honest with them. He builds a lot of loyalty and then uses that as currency to tune his squad into a group that is willing to put in for him.
Listen to any player that has played for him outside of our club and they'll all tell a very similar story. He's like a surrogate father figure for his teams. They respect him because he's got their back and is genuinely looking to improve them as people first then as footballers.
He'll give each player the individual treatment he thinks they need to succeed. Sometimes that's whooping their arse, sometimes it's giving them a cuddle.
