Another crucial Arsenal match, another dismal Mesut Ozil performance. The German playmaker's abysmal display against AS Monaco in the Champions League on Wednesday night could prove to be the straw that breaks the camel's back.
The £42.4 million signing has been an utter failure at the Emirates Stadium - arguably one of the worst pound-for-pound signings of the Premier League era - and the most concerning thing for Arsene Wenger is there appears to be little light at the end of the tunnel.
Ozil has looked disinterested, unmotivated, even a little sad since joining the Gunners. Yes, his laid-back approach can be misinterpreted, but you only get away with looking that chilled on the pitch if you're producing the goods.
Ozil's fall from grace
So much was expected of Ozil when he arrived at Arsenal in the summer of 2013 - and understandably so. This is the player widely considered one of the best - if not the best - playmaker in world football during his three-year stint with Real Madrid.
Ask your average fan to name the world's best No. 10 today and nobody would say Ozil. Not even the most blinkered Arsenal supporter.
And it's not just your every day man in the street who believes Ozil has regressed since joining Arsenal.
Neville pans Ozil
England coach Gary Neville, working for Sky Sports during Arsenal's shock 3-1 defeat to Monaco, said mid-match: "Ozil continues to confuse and amaze.
"I imagined he would be a world-class player, but he hasn't materialised."
If Ozil continues to perform this badly between now and the end of the season, Wenger should cut his losses and sell for the highest price this summer.
The French coach's faith in Ozil hasn't been repaid, despite the fact he has given the player more than enough chances to shine over the past 18 months.
Alex Oxlade-Chamberlain may have given the ball away for Monaco's third goal, but he still did more good for the Gunners during his 22 minutes on the pitch than Ozil managed in 90.
Too many pathetic displays
There really was no point in him being on the pitch - respected French newspaper L'Equipe generously rated him 3/10 - and his lacklustre showing wasn't even a surprise.
He was arguably even worse during last season's Champions League last 16 first leg against Bayern Munich, missing a penalty inside the opening 10 minutes before performing his standard disappearing act.
While he was lucky to avoid being hounded out of Arsenal following his laughable display against Liverpool at Anfield 12 months ago.
Ozil wasn't the only Arsenal player who performed badly against Monaco - they were all pretty terrible in their own unique ways - but the former Real Madrid star has shown nothing over the previous year-and-a-half to suggest Wenger ought to stick by him.
Summer exit looms for Ozil
Wenger should take a leaf out of his old adversary Sir Alex Ferguson's book.
The former Manchester United boss signed the world-class Juan Sebastian Veron from Lazio for a record £28.1 million fee - and sold him to Chelsea two years later for £15 million because the move simply didn't work out as planned.
The same fate awaits Ozil this summer - although he can dream on if he thinks Chelsea will sign him, even if Jose Mourinho remains a fan.
