When Mason Greenwood, Marcus Rashford and Anthony Martial started nine of Manchester United's final 11 games of last season it looked the club had an attack to build around for years to come.
With Jadon Sancho the club's top priority in the summer transfer window there was plenty to like about the way Ole Gunnar Solskjaer's side were shaping up going forward.
Alas, that excitement has dimmed of late. Sancho didn't sign and that front three that excelled after the season resumed in June have barely featured together this season and all have had problems to battle.
Martial was sent-off against Tottenham and banned for three games, Greenwood had his indiscretion on England duty and isn't at his best this term while Rashford's relentless workrate (he's played in 25 of United's 26 games since June 19) forced him out of the latest England squad with a shoulder injury.
In those 11 games that trio started together late last season they scored 14 goals, but so far this season they've started together only twice, in the win at Brighton in the Premier League and then for just 28 minutes against Tottenham before Martial was dismissed.
None of the trio scored in those games, but they do have 11 between them again this season, with Rashford claiming seven of them. There was even the sight of all three on the same scoresheet once more against RB Leipzig, when Rashford came off the bench to score a hat-trick in the 5-0 win
But with Greenwood out of the side at the moment and Rashford struggling with injury, the wait to reunite them in attack might extend beyond this weekend.
That's not ideal for Solskjaer, who finds his options for the front three limited after United's failure to land Sancho this summer. Daniel James has continued to struggle for form and while Juan Mata started the season brightly he has struggled to maintain those levels against Istanbul Basaksehir and Everton.
So it might be that Solskjaer needs to field a new front three again when West Brom visit Old Trafford on Saturday night, and it could well be that United's attack has a new spearhead.
Edinson Cavani scored his first goal for the club in the win at Everton before the international break and maintained that form with his 51st goal for Uruguay on Friday, in their 3-0 win in Colombia. The 33-year-old played 78 minutes in that game, another vital workout in his quest to reach full match fitness, and he will top that up against when facing Brazil on Tuesday night.
If either Rashford or Greenwood miss out for United on Saturday then Cavani has to be the man to come in. His goalscoring record is supreme and the concerns many fans had when he was signed on deadline day have eased with his contributions off the bench so far.
He only played eight minutes at Goodison Park but he took his goal well and has looked sharper with each of his five cameos from the bench.
While the Uruguayan is unlikely to be played anywhere but centre forward, United's other attackers are versatile. All of Rashford, Greenwood and Martial can lead the line, but all can come off the flanks as well.
If Cavani starts against the Baggies then it could see Martial returning to a role on the left of the front three with, ideally, one of Rashford or Greenwood on the right.
Solskjaer doesn't have the options he wants in attack right now, but Cavani's hunger to embrace a new challenge was a key reason United committed to signing him late in the summer window, and the time is coming to give him his first start in the Premier League.
