Just do it.

A slogan for the ages that helped propel Nike to become the world's premier sports brand. It's three words that suggest action, swift and clear and decisive. Rangers should take heed.

For years now the club has lacked a goalscorer. What about Alfredo Morelos I hear you cry? Well, the Colombian may have been a one-man wrecking crew in the Europa League where he remains the competition's third-highest goalscorer, but in the Scottish Premiership his top season tally was just 18.

Even that was an anomaly. As an average, Morelos was a 13-goal striker in the league across his six years in Govan. That's nowhere near what a main man needs to be at this level to secure titles.

The incumbent forward, Cyriel Dessers, is an honest trier but lacks the quality to be a game-changer. He misses huge chances with regularity and lacks the finesse to link the game to a standard required at the cutting edge of our game. He isn't the answer. Clement knows this, and you can expect him to move on with everyone's best wishes.

Many more have tried and failed to offer a spark similar to what Kyogo brought to Celtic under Ange Postecoglou. So this isn't a short-term issue. A 20-25 league-goal striker wins you titles and cups. Rangers could do with finding one.

And yet, an hour's drive down the M8 there's a simple, zero risk solution to all this. Last season, Lawrence Shankland scored 31 goals for Hearts. He scores all types, long rangers, volleys, free-kicks, poached trundlers and is capable of the truly spectacular.

He's also a reliable penalty kick taker, something that will be needed if James Tavernier is to move on as expected. A Rangers fan growing up, Shankland is also understood to be open to a move to his boyhood heroes should they come calling. So why hasn't an offer gone in?

Some key figures at Rangers have asked the same thing but while manger Philippe Clement and transfer guru Nils Koppen respect the player, they are not sure he fits the bill in terms of his age at 29, the expensive price of the transfer for a player with only a year on his contract nor his ability to play in a team that expects its no.9 to engage in a highly energetic press.

With Europe and Celtic matches in mind, this is understandable but it's to overthink the rough and tumble of the rest of Scottish football. We are a gloriously archaic league at times and the combined impact of our weather and how referees enforce the laws of the game with leniency means pure football ideology can be a tough solution to the problems posed. Postecoglou managed it but there's a reason this true one-off moved to a Premier League giant.

For other coaches in the Scottish game, there's a massive emphasis on set pieces, eliminating mistakes and being defensively robust. If you add quality in attacking areas to that, you can be a serious force.

Look at Kilmarnock's brilliant rejuvenation under Derek McInnes or Celtic last season who were all about moments. It wasn't always pretty or cohesive, but they got there most of the time. Their quality was what showed up in those final weeks when the title-going got tough.

Shankland may be 29. It may take the guts of £3m to force Hearts to play ball. But he offers what nobody else does - guaranteed Premiership goals. It doesn't matter how talented, or skilful or quick a player coming in from abroad is, they don't give you that.

We've seen players with outstanding technical quality come in and struggle in the rough house that is our game. Look at Sam Lammers just last season, a dud in Scotland and a revelation in the much tougher Dutch top flight.

That certainty is worth paying a premium for. If Rangers want to win titles and cups in Scotland, they need players who are proven performers. When it comes to Shankland they need to adopt a Nike mentality and Just Do It.
