When Alexis Sanchez joined Manchester United in 2018, the deal was hailed as a real coup given the Chilean's pedigree and recent form.
The season before, Sanchez had netted 30 goals and provided 18 assists in 51 appearances in all competitions for Arsenal - a staggering 48 goal involvements - on the way to helping the Gunners lift the FA Cup.
United had to fight off stiff competition from neighbours Manchester City, with Pep Guardiola particularly keen on a reunion with Sanchez after their spell at Barcelona together.
But United won the race after offering Henrikh Mkhitaryan to Arsenal in exchange, and Sanchez signed a four-and-a-half deal at Old Trafford, on reported wages in excess of £400,000-a-week.
The move was expected to help United bridge the gap on City and launch a serious title challenge, but what followed was an extraordinary fall from grace for one of the Premier League's elite attackers.
Sanchez opened up on the struggles he faced after moving to Manchester - admitting that the mid-season move had been tough to get to grips with.
“Seeing as I demand a lot of myself, I expected something better,” he said.
“After my arrival at United, it was hard to change everything very quickly. The change of club was something that was very abrupt - it was the first time I’ve changed clubs in January - but many things have happened in my life that are difficult.”
The comments came soon after a report that coaching staff at Manchester United were becoming concerned with Sanchez’s ‘miserable demeanour’ at the club's Carrington training ground.
It was also claimed that the attacker often sat on his own to eat and was an isolated figure, similar to how Angel Di Maria was viewed at Old Trafford during his short stay in Manchester.
Sanchez only played 45 games for United and mustered five goals before joining Inter Milan on a season-long loan in August 2019.
On Wednesday, Inter finally made the move permanent and ended one of the most disappointing chapters in United's transfer history.
"We have agreed [the deal]," United boss Ole Gunnar Solskjaer told BT Sport after his side reached the Europa League quarter-finals with a win over LASK.
"He has enjoyed his time there. He is a top player but for whatever reason we didn't see the best of him.
"He is a top professional and we wish him all the best."
When Sanchez left Arsenal, there were concerns that the Gunners would struggle to replace the Chilean's goal output, but the departure has proved to be the right decision - especially with the eventual arrival of Pierre-Emerick Aubameyang.
