Stefan Struve will make his long-awaited return to action when he faces fellow Dutchman, Alistair Overeem, at UFC on FOX 13 on Dec. 13, 2014 in Phoenix, Arizona.

It's a fight that could prove to be "The Reem's" last, after dropping three of his last four bouts, with his most recent loss coming at the hands of Ben Rothwell, who knocked out the former K-1 champion in the very first round at UFC Fight Night 50 just a few weeks back (video).

Though Overeem hasn't quite lived up to everyone's expectations since making his UFC debut back at UFC 141, not everyone is surprised by his lack of success inside the eight-walled cage. That includes Struve, who says most people -- including his friends -- thought Alistair was going to walk right into UFC and annihilate everyone.

But just because he was doing that to everyone outside of the promotion, Struve knew Overeem would have a hard time dealing with the increased level of competition that UFC has to offer.

That's why "Skyscraper" declared (via MMA Hour) that when you really break down his list of accomplishments before stepping into the Octagon, it's not all that impressive.

"Surprised? The competition, and the level of competition in UFC, is just really high. I said that to my friends and to people that asked me before he got into the UFC. They said he would dominate, be champion of UFC and annihilate everybody. But I told them to just wait and see. The competition in UFC, you can't really underestimate that. He was beating everybody outside of the UFC. But if you go to his record and also on K-1, if you really take a look at what he won and who he won against, then I'm actually not that impressed. Who did he really win against in a period where people were saying that he might be the No. 1 heavyweight in the world? Yeah, he beat Fabricio Werdum, but was it impressive? I didn't think so. He won K-1, but in the first round he won against a mediocre fighter. Then he beat Gokhan Saki when he had a broken arm. Then he beat Peter Aerts, who was pissing blood after fighting Semmy Schilt. So, if you really take a good look at it, it's not all that impressive. He was winning in impressive fashion, but not against the best guys in the world. Not in the UFC where the best talent is and has been."

But just to be clear, Struve doesn't think "The Reem" is overrated and admits that he does have skills when you let him fight his fight. But that's something the towering Swede won't let happen, as he plans on inflicting his own pressure in attempts to make his foe quit.

Struve, who has been dealing with heart issues over the last year (details), was set to make his comeback at UFC 175 this past July against Matt Mitrione. However, prior to walking out to the cage, "Skyscraper" fainted in his locker room and the fight was subsequently scratched.

Admitting he was "ashamed" at what happened, Struve also revealed that his fainting spell had nothing to do with his heart, but rather, increased tension and anxiety of stepping back into the cage.

Having said that, Stefan doesn't expect any setbacks as he gears up to make his long-awaited return.
