It has already been made pretty clear by events this season, that if Blackburn Rovers are to have any chance of winning promotion to the Premier League, their attack is going to play a big part in that success.

With 27 goals in 14 league games so far this season, Tony Mowbray's side are the Championship's top scorers by some margin, with the switch from a 4-2-3-1 formation to a 4-3-3 that was first introduced at Ewood Park when last season resumed after lockdown, starting to pay-off.

Of that front three that are leading the line, it seems as though there will be two mainstays to respective positions throughout the remainder of the campaign, if current form continues.

Sitting top of the Championship's individual scoring charts right now with 13 goals in 13 league appearances, it is hard to imagine that Rovers would want any Championship player other than Adam Armstrong leading the line for them at the minute at the sa.

On the left meanwhile, Ben Brereton, the only man to start every league game for Rovers this season, is finally starting to show the sort of talent they paid all that money to Nottingham Forest for back in the summer of 2018, and with goals and assists arriving in his game this season, he too, is starting to look undroppable right now.

However, on the right-hand side of that attacking three, the situation is rather different, with Mowbray fast developing an embarrassment of riches on that side of the pitch.

The rapid rise of 18-year-old Tyrhys Dolan at the start of this season, brought in on a free from Preston in the summer with a view to a stint in the under 23s that it now seems was never needed, had already started the mini-revolution in that position before many expected.

The late deadline day swoop for Liverpool winger Harvey Elliott on a season-long loan - who has wasted no time settling in at Ewood Park, even playing key parts in goals in the last two wins over Preston and Barnsley with defence splitting passes down the right, despite an otherwise quiet performance in those games - has since gone some way to boosting Mowbray's options in that position.

And then of course, there is the very welcome, and long-awaited, return to form of Sam Gallagher.

Having found himself struggling to make an impact while consistently on the right-wing in that aforementioned 4-2-3-1 much to the frustration of many of a Rovers persuasion, and then dropped to the bench at the start of the current campaign thanks to the form of Dolan and then Elliott, recent performances have suggested that Gallagher - like Brereton - is about to give the club some return on their not insignificant investment.

With two goals from the bench on the last two Saturdays sandwiching a stellar performance from the start against Preston last midweek - winning the penalty and red card that ultimately turned the game in Rovers' favour - Gallagher is now making a big push to reclaim his place in the starting XI, giving Mowbray a very welcome variety of options.

So far this season, Dolan, Elliott, and now Gallagher have all shown that they are playing to a level that would be expected of a member of a team pushing for promotion, and that is something you feel Rovers simply have to exploit.

Considering the contrasting styles of the three, Mowbray can make things very difficult for opposition sides when it comes to preparing to face Rovers if he starts to rotate the trio of Dolan, Elliott and Gallagher on a fairly regular basis, especially in a season where there is very little time between games.

While teams should by now be well aware of the fact they will be defending against Armstrong through the middle and Brereton from the left when they are coming up against Blackburn, it makes it harder for them to setup to face Rovers if they do not whether they will have to cope with the physicality and finishing ability of Gallagher, pace and trickery of Dolan, or mobility and passing range of Harvey Elliott down the right.

But why is it that that position on the right hand side of attack that was such a source of source of disappointment for Rovers last season, could suddenly become so important for them in the current campaign?

Obviously, one answer is that Gallagher, Dolan and Elliott are all upping their game and performing better on the pitch in order to remain above one another in the pecking order, but tactically as well, it could well be argued that aforementioned change formation could well be having a big effect here, particularly in the case of Gallagher.

Whereas as last season, the former Southampton man was playing as part of a three in attacking midfield, this season, he is playing slightly further forward more as part of an all-out striking lineup, at a similar distance up the pitch to an Armstrong or a Brereton, thus allowing him a greater sense of familiarity with the centre forward position he has played pretty much all of his career up until now, helping him to play something more similar to his natural game.

It is also worth noting that the pressure on Gallagher from a defensive perspective has reduced, which is also likely to be helping him.

Now that there are three midfielders behind him rather than two, there is less expectation and requirement on him to track as deep back every time Rovers are defending, given they have that extra cover from the centre of the park, helping him physically when it comes to the runs he is making, given that is not the strongest part of his game.

Another benefit to that formation change Rovers have seen this season, is that both Joe Rothwell and Lewis Holtby, two others who struggled to really make an impact in attacking midfield last season - are now flourishing after dropping deeper down the pitch now that that extra position has opened up in the centre of midfield.

As a result of that, the control Rovers now have in midfield is greater than in the past, and the chances that the likes of Gallagher, Elliot, Dolan, Armstrong and Brereton are getting are now both more frequent, and clearer cut - Armstrong hasn't even had to score a goal from outside the box yet this season.

It seems therefore, that after much experimentation and negotiation, Blackburn have now found a system that suits the attacking, free-flowing style of play Tony Mowbray has been so desperate to introduce to the club, and those within his squad, are starting to benefit.

Plenty of things will of course have to go right if Rovers - or indeed the vast majority of Championship clubs - are to win promotion to the Premier League this season.

But with the options they have established for themselves, and a setup they have now made their, things do at least not have to be going right for everybody all the time, and that at least, is a very useful insurance policy to have.
