Alexis Sanchez was supposed to be a landmark new signing who would revolutionise Manchester United's attack and help them compete with the rampant Manchester City.
The Chilean's time with Arsenal had seen him go from a nearly-man at Barcelona to one of the world's best players and his contract situation at Arsenal brought about a three-way fight for his signature.
The Gunners certainly wanted to keep him, Pep Guardiola openly courted him, but United stole in and blew everyone out of the water with their offer.
It was the move that dominated the January transfer window and the hype on his arrival was enormous.
But it's been downhill from there.
Sanchez has struggled to find a place in Jose Mourinho's side, not finding any kind of rhythm and looking nothing like the player United had hoped they'd signed.
Talk of Sanchez not fitting in off the field has kicked off in recent days - suggestions that the 29-year-old eats alone and rarely talks with his teammates has created some worry about his future at Old Trafford.
Speaking on Eamon Dunphy's The Stand Podcast, an ex-Arsenal coach isn't at all surprised at the situation - it's just who Sanchez is.
"From the information I have and what I know, Sanchez is not the easiest of characters on a day-to-day basis," said former Arsenal player and coach Liam Brady.
"He does his own thing and he is not part of the group, but all the other players forgave him for that because when he played for Arsenal he was outstanding in the early part of his career at Arsenal.
"He was an example to the Arsenal players for how hard you need to work in his early days, but going up to Manchester and being on that kind of wage compared to the other lads, you need to do as you are asked and do what the other players do."
Whether that will be possible for Sanchez, however, Brady has doubts.
"He has always been a bit of a solo player," he said.
"Maybe he has not settled in Manchester. He may be looking around thinking he should not have gone there."
There's still plenty of time for Sanchez to fit in at United, with Mourinho soon after his arrival that we won't see the best of him this season.
Man City's pace at the top of the league meant this year was virtually a write-off for United, anyway - next season will be the real test of the Sanchez signing.
