When Manchester United swapped Henrikh Mkhitaryan for Arsenal's Alexis Sanchez in January, everyone thought the Red Devils had got the better end of the deal.
How wrong were we?
It's been 11 months since Sanchez made the switch from London to Manchester and in that time he's only scored three Premier League goals and recorded five assists.
Sanchez's decline has been staggering and now there are rumours the 29-year-old - who currently earns £500,000-per-week - could leave United in January.
China has been tipped as a destination, but Jose Mourinho believes Sanchez wants to stay and do better for the club.
"I don't think so because he has never told me that he wants to leave. He never told me that he's not happy to stay," said Mourinho in November, per Sky Sports.
"He is playing like the team. He is improving, like the team is improving, when he plays he is giving us his personality.
"His desire is to play and to produce for the team and [he is] trying to adapt to the way we play and vice versa.
"Can he do better? We all can do better. I can do better, he can do better, all the players can do better."
Sanchez's misery at United was compounded last week as Mourinho confirmed the Chilean will be out for a month with a hamstring injury.
But in an 11-month period full of lows, arguably the lowest was what happened in a recent sprint test during United training.
According to the Independent, Sanchez lost in sprints to none other than Juan Mata, who is one of United's slowest players.
If anything sums up Sanchez's decline it's losing in a race to the Spaniard, because he used to be one of the Premier League's fastest.
What the future holds for Sanchez remains to be seen, but the simple fact of the matter is he's not nearly as good as he used to be and his decline isn't about to slow down.
