Manchester United will experience far stiffer tests of their Champions League credentials than Sabah FK gave them at Old Trafford.
In fact, it would be no surprise if the Azerbaijani champions were by some distance the weakest of the eight league stage opponents Michael Carrick’s side will come up against.
However, there were some important lessons for head coach Carrick to absorb.
The biggest of them is that United are a much more effective unit when Benjamin Sesko starts.
This was the first time the Slovenian had done that since the Liverpool game last March, when he finally accepted he could no longer play through the shin issue that had been plaguing him for a number of weeks.
It had been hoped Sesko would be fit for the start of the Premier League season.
As it turned out, he was only at the stage where he could be brought on as a substitute in the second half of the opening-day trip to Hull. The same also applied for the subsequent outings against Ipswich and Everton.
It was Sabah’s bad luck that Sesko was fit to start against them – and it showed.
At 6ft 5in, the 23-year-old has a physical presence United’s other strikers lack.
Amad Diallo’s current absence has robbed Carrick of the option to start Bryan Mbeumo at the head of his attack, as he did during pre-season, but Matheus Cunha is not without ability in that role.
The problem is that the Brazilian likes to drift and drop back into space, which leaves a gap at the apex of Manchester United’s attack.
Sesko offers a totally different threat. He pushes defences back. He is not easy to dispossess. He runs at opponents rather than away from them.
He also scores goals.
At Everton, it was his size that allowed him to convert a close-range header that looked set to give United victory but ultimately didn’t, because of Ainsley Maitland-Niles’ stunning late strike.
Against Sabah FK, Sesko had threatened with an impudent first-half back-flick before Mbeumo sent him running beyond the visitors’ defence.
Sesko had clarity of thought, swiftly moving the ball past goalkeeper Stas Pokatilov before steering the ball into an empty net.
