Mesut Ozil's Arsenal future remains a serious question and head coach Unai Emery is doing very little to dissuade suggestions that he wants to rid of the German playmaker.
World Cup winner Ozil, 30, is the highest paid player after inking a massive £ 350,000-a-week deal last year.
But he is down the pecking order under Spanish boss Emery, who of course only arrived in north London after Ozil inked his new deal.
Left out of Bournemouth away because the game would be "too physical" according to his manager, Ozil has since played just 155 minutes in the Premier League, across 10 matches.
In six of them he has been out of the squad completely, whether due to injury or other reasons.
In December, he didn't make the squad for the Carabao Cup quarter-final against Spurs – despite being fit – with youngster Eddie Nketiah preferred in the 18-man squad.
Emery has been frustrated with Ozil's work rate and contribution to the team but knows he has little chance of offloading the player – unless the club's hierarchy is willing to subsidize any potential move.
That is causing something of a standoff, because Ozil has no place in Emery's starting side; the Spaniard prefers both Alex Iwobi and Aaron Ramsey, despite club chiefs refusing to hand the Welshman a new deal and Ramsey set for Juventus.
On the bench for a second game in succession against United, Ozil was brought on with 25 minutes remaining and the Gunners trailing 2-1.
The hope was to inspire the side – instead of being heavily floundered, if Arsenal struggled to create opportunities and United behind a third, through Anthony Martial, to secure a FA Cup fifth round place.
Asked post game about Ozil and why he didn't start, Emery responded: "He played".
When the response was "why did you not start him?" Emery succinctly added: "Because I think I can play other players."
And right now, that tells you everything.
Emery has little time for questions about a player that, simply, he doesn't want in his page
Ozil can be brilliant on his day, but those days have been all too infrequent, not just under Emery, but in the last 18 months for his club.
The Spaniard wants his side to play with intensity, but feels ozil's game lacks precisely that.
Jermaine Jenas, speaking on Match of the Day, picked out the difference in Ozil and Alexandre Lacazette, a player who has forced his way into the
"Lacazette, your number nine, your center forward, coming back and winning the ball on a couple of occasions," said Jenas.
"That epitomises what Unai Emery is trying to do here. It's infectious. "
" that that's all he asks for, for him to be a part of it. "
Emery's latest post-game response to his Ozil conundrum suggests is done waiting.
