This is more like one being strapped to the back of a rocket and the other deep-diving to the bottom of the Mariana Trench.
One team spends more than £100 million on seven players, the other has picked up two free agents who managed just 27 league starts between them in the last two seasons.
The last two times Tottenham made the short trip to the Emirates to face Arsenal - as they will do this lunchtime - they were pummelled, losing 5-2 on each occasion. This year, there's reason to believe it will be different.
A single point separated the two teams last season. And while Spurs, even without Gareth Bale, look better-drilled, deeper and more talented than last season, morale among the Arsenal faithful could scarcely be lower.
If there is such a thing as "best practice" in transfer dealings, Spurs have come pretty darn close. They got the three signings they needed - a box-to-box midfielder (Paulinho), a genuine winger (Nacer Chadli) and a penalty box goalscorer (Roberto Soldado) - done by August 1, giving them time to develop chemistry and absorb Andre Villas-Boas' system.
They picked up Etienne Capoue, an up-and-comer who represents a calculated risk, on the eve of the season. And then, as the Bale sale got closer, they made three more acquisitions on Friday: a no-nonsense centre-back (Vlad Chiriches) and two of the best young attacking players in Europe (Erik Lamela and Christian Eriksen).
In each of those cases, they were careful to close the deal while there was still some level of uncertainty over Bale (at least in the eyes of the sellers) meaning they didn't go into negotiations with their wallets bulging with fresh cash.
Arsenal's woes, on the other hand, are well-documented and it has been a familiar story over the past few years. Could this be the season Spurs finally overtake them, not just in the league table, but as the main power in North London?
There have been so many false dawns that you are reluctant to say yes. On the other hand, it's hard to come to any other conclusion.
THERE you were thinking Jose Mourinho had developed an immunity to Guardiolaphobia when suddenly he takes you right back to square one. Ahead of Friday's European Super Cup he was told he had beaten the former Barcelona boss just three times in 15 attempts.
The Chelsea manager's response was the numbers were "wrong - very wrong". He rattled off a list of the trophies he had won and which Barcelona had not until, perhaps realising the inanity of what he was doing, he retreated and said: "Maybe you are right and I am wrong, but I don't care. It's not important for me."
Those were warning signs. Fully-fledged "Old Mou" stormed back after Chelsea's defeat on penalties against Bayern Munich in Prague to confirm that, yes, the venom is alive and well.
"When I play Guardiola he always has an extra man," Mourinho said. "If you love football passionately like I do, you don't ruin a great match by sending somebody off in that way."
He was referring on this occasions to Ramires' second yellow card. The midfielder's challenge on Mario Gotze, was a classic "should have known better" tackle, but the implication is silly. Should officials simply stop applying the laws of the game so as not to ruin a "great match"?
And did it really ruin the game for Chelsea, given that they took the lead early in extra time and only conceded the equaliser in a mad last-kick-of-the-game goalmouth scramble? Then Mourinho reverted to his "best team lost" mantra, to which Guardiola offered his own neat symmetry, saying "the best team won".
Statistics overwhelmingly favour Bayern, but you would expect that given that they twice had to come from behind and played for more than 35 minutes against 10 men.
The way the game unfolded, on the other hand, tells you Mourinho had the upper hand in the first half, partly because of Guardiola's penchant for experimentation (like putting full-back Phillipp Lahm behind centre-forward Mario Mandzukic) and partly because Chelsea were devastating on the break. But then Bayern made their adjustments and Mourinho's crew were pushed deeper and deeper.
What's more, he only made his first substitution after the Ramires red, when Chelsea looked tired and ragged well before that. The good news? If you're a neutral, there will be many more chapters written in the saga of Pep and Mou.
UEFA'S decision to allow the top women's leagues in Belgium and Holland to merge last season continues to have knock-on effects.
Russia and Ukraine are the latest nations to have mooted the possibility of combining at the top level, a move that would see the likes of Dynamo Kiev and Shakhtar Donetsk play in the same league as CSKA Moscow, Zenit St Petersburg and Spartak Moscow.
It has been done - and is working well - in ice hockey, where the Kontinental Hockey League (KHL) is now offering some competition to North America's NHL.
Michel Platini addressed this in Monte Carlo on Friday, admitting Uefa have had several requests in that regard.
"Some leagues are asking to form associations," he said. "They feel it is better for them financially and can make them more competitive. Of course, Russia and Ukraine are not leagues in difficulty, so it may not be the case for them. But it's a debate we're following."
Sometimes trying to read Uefa is like trying to read tea leaves, but the implication is that the genie is out of the bottle.
The Belgium-Holland women's league has opened the door and now others want to step through it. Could Scotland be involved one day, possibly resurrecting the old Atlantic League concept with Portugal, Holland and Belgium?
There's a long way to go. But it's certainly more a of a possibility today than it was two years ago. Platini's words only confirmed that.
