There was a time when Anderson was the hottest prospect in world football. He was the Lucas Moura of that time.
Since then he's flattered to deceive. He flashes brilliance before fading into the background. A few years ago he played a talented Liverpool midfield off the park and fans thought he'd arrived, but it proved to be a false dawn.
He became a bit-part player before reemerging last season, forming a hugely-impressive partnership with Tom Cleverly.
The duo seemed to have a telepathic understanding, taking turns attacking and playing beautiful one-touch football.
Cleverly's injury woes put paid to that partnership and Anderson faded away again.
If United can keep them fit, they could form their midfield for the foreseeable future. Anderson is 24 and Cleverly 23 so they have years of football left in them.
I can't help but feel that Anderson has grown up this past year, as the boy United signed finally became a man.
He has been fond of the high-life, caught in nightclubs when he shouldn't, wrecking his expensive car and admitting he would cry if he had to cut his dreadlocks.
This year he returned with a clean haircut and ready to knuckle down. United will hope the talented Brazilian can finally deliver on his promise.
If the duo can repeat their form of last season, United might finally replace the legendary Paul Scholes.
