Blackburn Rovers are having to make do without leading frontman Adam Armstrong this season as the prolific forward was finally tempted away to the bright lights of the Premier League during the transfer window.
After joining in January 2018 on loan from Newcastle and then making the move permanent six months later for £1.75m, he spent three seasons at Ewood Park, notching eight goals in his first term.
Armstrong improved steadily, with 17 goals the following campaign, while he had a real stand-out season last year, with a stunning 29 strikes in 43 appearances, including a hat-trick in his last outing for the club, his third treble.
Still aged just 24, that kind of output was always going to lead to interest from top flight clubs, Southampton eventually parting with £15m for his services last month after losing their own talisman Danny Ings to Aston Villa.
He has hit the ground running too, scoring on his debut at Everton, but the forward's departure left Rovers boss Tony Mowbray with the job of replacing him, something he couldn't manage to do ahead of the deadline passing on August 31.
Speaking about his inability to do so, he told Lancs Live: “I don’t feel let down, I understand the process.
“Football is very difficult when you’re juggling four, five, six different options.
"Option four, five and six could be done now, but number one and two is what you want in your mind so you hold off and then four and five sign for someone else, but six is still there, but you still want one and two.
“Those things can happen. You wait for one or two and then six disappears and then you have one, two or three.
“For reasons other than financial, these deals didn’t happen.
"It was a frustrating day, a frustrating night, because I felt we were going in the right direction and the team was going to be so much stronger."
To replace Armstong's goals, Blackburn will look to Ben Brereton, now becoming a cult figure after his exploits with Chile, while Sam Gallagher is tasked with increasing his productivity as well.
It wasn't just Armstrong's departure that Mowbray had to address but on-loan Liverpool teenager Harvey Elliot, who bagged seven goals and 11 assists last term to earn a nomination for the EFL Young Player of the Season award, with the youngster returning to Anfield and making his mark in the Reds side.
Although unable to bolster the striking department, it wasn't a barren transfer window, Mowbray using the loan market to strengthen the supply-line, bringing in German winger Reda Khedra from Brighton, plus Liverpool midfielder Leigh Clarkson, a boyhood Rovers fan.
England U20 international Ian Poveda has also arrived from Leeds, while Mowbray went to Brighton once more for defender Jan Paul van Hecke, as he splashed some cash on deadline day to acquire the talented and highly rated Tayo Edun from Lincoln City.
Mowbray did move some out of his squad, with Stewart Downing retiring, while Lewis Holtby was released, the long-serving Elliot Bennett moving on, as did Charlie Mulgrew, Corry Evans and Lewis Thompson.
Despite the changes, Rovers started the campaign positively, with a 2-1 win over Swansea, but then saw their Carabao Cup dreams over when defeated by Morecambe, before drawing 1-1 at Millwall.
A 2-1 triumph at Nottingham Forest saw Rovers make it seven points from nine, before they suffered a first league loss, going down at home to promotion favourites West Bromwich Albion.
Rovers did get another point in their 1-1 draw at Middlesbrough ahead of the international break, as they sit in 10th, with home games against Luton and Hull this week to try and improve on that standing.
Team news: The Hatters are almost fully fit for the clash, with Sonny Bradley and Luke Berry both getting their first minutes this season for the Development squad on Tuesday afternoon.
Jordan Clark, Henri Lansbury and Cameron Jerome are all looking to be involved, with Dan Potts back in training as well too, while Danny Hylton is getting closer to returning as well.
For Rovers, Ryan Nyambe is fit after a hamstring injury, but Bradley Johnson won't make it back yet following his own hamstring problem and Joe Rankin-Costello is still absent with a broken metatarsal.
Tayo Edun is out with medial ligament damage suffered at his previous club Lincoln, while FIFA sanctions are anticipated to keep striker Ben Brereton out.
Long term absentee Bradley Dack is looking at January for his comeback from an anterior cruciate ligament injury, with Scott Wharton missing too.

We've got form: The Hatters have a fairly shocking record at Ewood Park since their first visit in March 1938 when they drew a Division Two contest 2-2.
It took the Luton some 10 matches and 22 years to enjoy their first victory, triumphing 2-0 in a Division One clash in April 1960, with Joe McBride and Billy Bingham scoring.
That led to a six game winless run, Town failing to score in any of the matches, a sequence spanning 21 years, as their only positive result was a goalless draw in October 1978.
However, they stopped the rot with a 1-0 Division Two win in 1981 through David Moss's penalty, following that up with a 2-1 victory in the first season back in the Championship, James Collins and Matty Pearson on target, before defeated 1-0 last term.
In total, Luton have won three, with five draws and 12 defeats from their 20 trips, scoring 11 goals and conceding 29, failing to score in 12 of the fixtures.
Last time out: Luton looked to be on their way to a well deserved point at Ewood Park last year only to concede with five minutes to go when they switched off from a quickly taken free kick allowing Adam Armstrong to score from close range.
The Hatters thought they had rescued a point in stoppage time, only for Harry Cornick's goal to be disallowed for offside.
Hatters: Simon Sluga, Matty Pearson (Martin Cranie 72), Dan Potts, Tom Lockyer, Sonny Bradley, Glen Rea (Kal Naismith 88), Pelly-Ruddock Mpanzu, Jordan Clark (Sam Nombe 88), Kiernan Dewsbury-Hall, Harry Cornick, James Colins (Danny Hylton 64).
