Just want to start off by saying this is my first fanpost, so hope you like it :).
These two players are both fantastic, versatile, fill places we lack depth/quality depth in. Where do they play? Well I'm sure you all know but Seydou Doumbia plays as a center striker (and, in my opinion, is much much better then Torres) and can also play and the left wing, and can cut in and strike with his right foot. Hulk is a right winger who cuts in with his left and scores with a HULK SMASH, he can also play as a centre striker.
So Seydou Doumbia is an Ivorian, which is something that we don't have at the club, and is a need, and he's a Chelsea Fan :D. I've watched him in the Champs league (we won) and have been impressed, and 5 goals in 5 games in the hardest cup competition in the game is no small feat. Not to mention that he's FASTER THEN RAMIRES, yes, he's faster then the player who you could lob a ball in with a defender marking him closer to that area then him, and be left miles behind. His finishings also better. His first touch has some room for improvement, but a great player who I've wanted since he was just 5 million pounds :)
Hulk, THIS GUY IS A BEAST. Im a major fan and I really want to wear a hulk mask when going to a Chelsea match, he looks like a Hulk, if this guy was running at you, especially if your a fullback, you'd probably start running. He has a glorious left foot and is pretty good at dribbling, his assist charts are pretty high, so I don't know what's up with all the Sturridge comparison (don't get me wrong, I really like Sturridge, shame he's out of form.) There's this channel on Rogers (425 for those of you who want to know) which always shows football, 24/7. Unfortunately it only shows games from Italy, Frances, and the Europa league, luckily I use it as a pretty good opportunity to scout players from said matches, and I saw Hazard and Hulk frequently. Hazard's great, but Hulk was Beast, he destroyed the defenses, scored stunners, made lots of assists, and did it all on the wing, 53 games with 36 goals and 21 assists from the wing is no small feat,(that was in 2011) and he got even more prolific in the 2011-2012, with 38 games with 21 goals and 15 assists, again from the wing. Great player.
Now I like both, and wanted them both and for Chelsea to forget about Hazard, but that's not gonna happen. So which one would I prefer? I would prefer 24 year old Seydou Doumbia who is 14 million pounds less then Hulk, a year younger, and his main position is CF, which is a much bigger need then the wings with Hazard and Rambo.
