For the remainder of Loris Karius' career, his name is going to be synonymous with the unfortunate events of May 26, 2018.
The goalkeeper's two errors in the Champions League final handed Real Madrid a 3-1 victory and in the process, all but ended his Liverpool career.
Far from vilifying his compatriot, Jurgen Klopp persevered with him into pre-season, before further mistakes against Tranmere and Borussia Dortmund convinced the Reds' boss to sign £67million Alisson Becker.
After that, securing a permanent move away from Anfield was always going to be difficult for the 25-year-old, with his stock so incredibly low.
Fortunately, Besiktas agreed to a two-year loan spell in the hope he could rediscover his confidence in the Super Lig.
That's not to say things have been plain sailing for him in Turkey. He has kept just one clean sheet in eight league appearances and has not even been guaranteed the number one spot, vying with Tolga Zengin of late.
Karius has made a number of costly errors already, which led to reports that Besiktas were going to send him back to Merseyside earlier. That really would have been a devastating blow.
Not only were those rumours wide of the mark - his agent quickly dismissed them - it seems Besiktas are, in fact, more likely to sign the shot-stopper on a permanent basis.
Besiktas are impressed
The club's president Orman told Turkish outlet Harberle, per Sky Sports:
"Karius is an excellent keeper, God willing we will sign him on a permanent transfer.
"These stories [of him returning to Liverpool] are complete nonsense.
"Give Karius some time is all I'm saying. Karius has a lot of work to do but give him time."
According to a recent report in the Liverpool Echo, a clause in Karius' loan deal means Besiktas can sign him for £7.25m, in addition to their initial fee of £2.25m - in just under two years' time.
That will depend on appearances and performance markers, such as whether Besiktas qualify for Europe.
If a deal comes off, it'll be a very positive step for Karius on his road back towards normality.
Every footballer has psychological hurdles they have to overcome and that is especially true of goalkeepers who have made high-profile howlers.
In spite of everything, Liverpool fans will be hoping he continues to impress his new club.
