He's doing well for Tottenham, but is he doing Champions-League-finalist well for Tottenham? Will he single-handedly win Real Madrid or whoever his next club may be the league title? No. He may turn into that player, but I don't see it.
That's why this question is both highly controversial and enjoyable. Why shouldn't a few individuals fly in the face of public opinion? And let's be honest, it's not as if I'm calling into question Lionel Messi's abilities, which by now are indisputable.
Bale has been playing well in a Tottenham team that suits him. They play with wide players who attack the furthest part of the opposition final third and drill crosses into the centre for a striker. It's effective, but does that mean he'll be a success wherever he goes?
There are too many examples of good players moving to teams who do not totally suit them. But maybe this one goes a little further than just playing to your strengths.
Should Cristiano Ronaldo leave at the end of the season, is Bale the player Real Madrid want to replace him? Bale is not a bad player, but I will continue to swing the bat toward this question: is he good enough for Real Madrid?
Ronaldo is a player who can score 60-plus goals in a calendar year. If he does decide to move on for one reason or another, shouldn't the main area of focus be to bring in a player who can replicate or come close to those numbers?
Bale would hypothetically come in to play in the left-wing position, but Ronaldo is not a winger, or at least he's not used as one for Real.
The Portuguese is a free-scoring machine who operates from that side of the pitch because it suits him. It also suits Angel Di Maria to play from the opposite wing for a reason that's as clear as day. Can Bale be effective if playing in a similar manner but from the right side?
Then there's the matter of the transfer fee. Tottenham hold Bale as their most valuable asset and value him somewhere in the region of £40 million. They held out for that figure when negotiating Luka Modric's sale last summer, but they didn't get what they wanted, and there's no guarantee they'll get what they want for Bale.
But even so, aren't there better players out there who can do far more for Real? Shouldn't the main area of focus be on Radamel Falcao if Ronaldo leaves? Why not opt for an actual striker such as Fernando Llorente, whose contract situation with Athletic Bilbao means he'll be a financially attractive target.
Real Madrid haven't hid their desire to bring Sergio Aguero back to Spain. They were the only club to rival Manchester City for his signature when Atletico Madrid sold him last year. Even he would be a far better player to help recreate Ronaldo's production.
If Real want to go for a player like Bale who can play wide and offer assists rather than goals, then why not look to Germany? Why not look to players like Mario Gotze, who has been so influential and so impressive for large spells of his time in the Borussia Dortmund first-team.
What a coup it was for Dortmund to pick up Marco Reus last season for 15 million euros. The former Borussia Monchengladbach forward fits the bill far better than Bale.
Bale could do well in Real Madrid's counterattacking system, but the overriding question here is whether he's value for money.
Is he a better option at left-back over Marcelo and Fabio Coentrao, two players who are considered among the elite of their position?
What if Ronaldo doesn't leave, then how much sense will it make?
As hard as it may be to come to terms with, what if there are far better players who can bring out the best and help raise the game of Real Madrid's most valuable attacking asset—Mesut Ozil?
Real Madrid need players like Falcao and Aguero for their abilities in front of goal. To help with the high technical standards of Ozil, the team need to be pairing him with players who are clearly good enough to stand toe-to-toe alongside him. Kaka is one of those players, but unfortunately the Brazilian has fallen out of favour with Jose Mourinho.
It shouldn't just be about a player who is hyped to the hill in England. Consistency comes into question for Bale.
But with Uefa's Financial Fair Play approaching and the team needing specific players to continue their success, Real Madrid need to be meticulous and smart in their approach to next summer's transfer market.
