Anyone who watched Manchester United's performance against Olympiakos in the first-leg of their last-16 Champions League tie will know they were far from their best.
In fact David Moyes' side looked distinctly average against the Greek champions, their early promise quickly lost and a final flurry of attacking chances too little too late.
United now have to score three without reply at Old Trafford to go through outright, and if their opponents find the net in the second-leg, then things will get really tough.
Tuesday's result was another disappointing match in a season full of them, with the impressive performance against Crystal Palace on Saturday evening appearing to be another false dawn (although Moyes was without both Juan Mata and Adnan Januzaj for the game in Greece).
One man watching the match was ex-England international Gary Lineker, and he believes that while United have defensive problems, it is their midfield that needs the most work.
There is nothing new in that thought. Anyone who has seen United play in recent times (and not just this season) will know how desperate they are for quality midfield reinforcements. But it was also something of an indictment of United's current players in that area.
"Straight lines, poor and predictable," Lineker said on Twitter.
He later tweeted a joke about United's season closing down faster than their defenders, seemingly making light of the side's failure to do just that against their most recent opponents.
And as if that was not enough, he later returned to the social media site to say he could not remember a more "abject, hopeless, forlorn performance" from United, referring to Olympiakos as mediocre opponents.
Whatever anyone else thinks, Moyes will know there is a considerable rebuilding job required at Old Trafford, and it may take longer than a single summer.
