It doesn't take a footballing genius to see that Marco Reus has been steadily improving over the last few seasons.
Such growth has culminated in him becoming recognised around Europe as one of the most intriguing prospects currently gracing the footballing world and, dare we say it, he looks like he could have it in him to get even better.
Of course, as is the case with all emerging talents who aren't produced at sides historically considered the greatest in the sport, he's tumbled head-first into the growing pile of exciting young players linked with a transfer away from the place that made him who he is.
In Reus' case it's Manchester United that are rumoured to be eyeing his situation with all the intent of a predatory bird circling prey and, with a mooted €35million release-clause on his head, it's more than likely that unless he pens a new deal with Dortmund, his club won't be in a position to refuse offers.
Call it a controversial opinion but I for one think that if Reus has any view to becoming one of the world's best players he needs to steer as well away from Old Trafford as it's physically possible for him to do.
To kick off the argument there is the perhaps pertinent points of trophies.
At Dortmund Reus stands in a good position to win silverware. To win the Champions League may be asking a bit too much of Jurgen Klopp's young side, but they will certainly be there or there abouts in the competition, not to mention a surefire favourite to run Bayern Munich close for the Bundesliga.
Alternatively at United Reus would find himself at a club that not only looks a cut under the required bench-mark for those hoping to compete for Europe's finest honour, but is also struggling to assert dominance in their own country.
Moyes is re-building his United squad and, although it's an admirable notion, Reus would be taking a step down in quality if he were to join the cause.
Then there's the matter of his personal development. With Jurgen Klopp having penned an extension until 2018, Reus has to carefully weigh up whether his skills will thrive elsewhere or whether or not remaining under Klopp's tutelage stands to benefit him the most.
With David Moyes he would be risking working under a manager who has little experience in dealing with players of his calibre and potential, as well as placing himself in uncertain surroundings. As aforementioned, the United squad is in undeniable transition and isn't currently a stable, proven environment desired by a player who's looking to better himself.
There's then the simply fact that at the moment Borussia Dortmund are a better side than Manchester United. The latter has a far more impressive legacy and therefore far more impressive name to add to the resume, but Reus would be taking a step down in the quality of football he is playing each week were he to decide to move to the Premier League champions.
His current employers are a force on the up, who are proving with each passing Champions League fixture that they now have what it takes to contend with the biggest names in the sport. In stark contrast the Red Devils are at the very best indifferent without Sir Alex Ferguson, and it could be a good few years before they come close to replicating the glory they enjoyed with him at the helm.
I'm not saying that Reus should opt for the likes of PSG, Chelsea or Arsenal- three clubs who have also expressed an interest- rather I'm deducing that the 24-year-old should remain at Dortmund for now achieve everything he possibly can with the club.
With the departure of Mario Gotze to Bayern Munich, and the fact that current key man Robert Lewandowski looks all but set to follow, Reus is set to take on a new impetus at the club, and could find himself the key figure in Klopp's exciting setup.
He should harness this opportunity and allow his abilities to grow in it, rather than moving to somewhere else just for the sake of the a big name and even bigger transfer fee.
It won't be everyone's cup of tea, and there is the chance that Reus could develop further with a move to the Premier League, but for me he stands to lose more than he will gain if he trades the yellow of Dortmund for the red of United.
