Liverpool fans have been keeping one eye on Loris Karius after his move to Besiktas this summer.
The German had established himself as the number one goalkeeper at Anfield, only for a disastrous performance in the Champions League final to completely derail his spell at the club.
Mistakes against Tranmere Rovers and Borussia Dortmund in pre-season eventually encouraged the Reds to send him out on loan, moving him onto Besiktas on a two-year deal.
Things started shakily for Karius on his debut, but he delivered a number of impressive performances to silence the doubters and deflect the constant attention placed on him.
However, the errors soon returned during a Europa League clash with Malmo where Karius inexplicably conceded a cross and was left dangling from his own crossbar.
Loris Karius in Besiktas
It even sparked reports in Turkey that Karius could be dropped for their next European tie, a fact refuted by his selection against Genk this week.
So, how did Karius fare on his return to the Europa League. In short, not all that well.
There were no high-profile mistakes from the 25-year-old, but he still endured a painful performance in Turkey with Besiktas succumbing to a 4-2 defeat.
Karius' display vs Genk
Two goals from Mbwana Samatta propelled the Belgians into a quick lead with Karius ending up in the net after the second, before another quick fire double sealed the win in the last 10 minutes.
Of course, a lot of the blame lies with Besiktas' questionable defending, yet it didn't stop criticism of Karius and journalist Mootaz Chehade couldn't help making a point about it.
He posted two tweets about Karius shortly after the game and it doesn't look good for him. Check out the posts below:
You've got to feel for Karius at this point.
Although the comparisons might be a little unfair, there can be no doubting that Alisson Becker has been a massive upgrade for the Reds and the stats speak for themselves.
Not only that, but Karius' performance against Genk certainly won't have fans wishing he was back between the sticks on Merseyside.
Kopites will have to hope that Karius can regain the form he showed in the early months of 2018 and hope his time in Turkey proves to be beneficial.
At the moment, he's doing little to convince top European clubs that he's good enough at the high level and the legacy of Kiev still hangs over him.
Karius has shown plenty of promise at Besiktas, but there's no doubting that the Genk drubbing was a step backwards.
