In considering Henry, Eto'o, Toni, Cassano, Adriano, Torres, and Ibrahimovic, here is how they stack up in different caterogies. Let me know what you think.
Box Play: The ability to play as an out-and-out center foward with a sole focus on goal-scoring a la Inzaghi. This player is at his best when the team is geared toward getting him to score.
1-Adriano 2-Toni 3-Henry 4-Ibrahimovic 5-Eto'o 6-Torres 7-Cassano
Versatility: The ability to help out in other areas including defensive midfield and playmaking. This depends chiefly on two factors: the players skill set (can he tackle? is he creative?) and his willingness to work above and beyond the call of duty for the team.
1-Henry 2-Cassano 3-Eto'o 4-Ibrahimovic 5-Torres 6-Adriano 7-Toni
Chemistry: The ability to accept conditions and put the needs of the team ahead of one's own desires/ego. This includes humility, temperament, respect for teammates... and determines how likely a player is to seemlessly mesh with the squad.
1-Eto'o 2-Torres 3-Henry 4-Toni 5-Adriano 6-Ibrahimovic 7-Cassano
Cost: here, the cheapest player is (1) and the most expensive is (7). Henry will NOT be cheap since we would have to fight off competition from top clubs to get him. I may be very wrong considering that Vieira went for what? A bag of chips and a can of pop?
1-Cassano 2-Toni 3-Henry 4-Torres 5-Eto'o 6-Ibrahimovic 7-Adriano
Practicality: This is how likely we are to get a player if we seriously commit to going after him (1) is most likely.
1-Cassano 2-Toni 3-Torres 4-Henry 5-Eto'o 6-Ibrahimovic 7-Adriano
Final Verdict: I've decided to ignore monetary concerns here and simply focus on how a player once acquired would fit in and perform.
Adriano, Ibrahimovic, and Toni are great strikers but I would remove them from consideration immediately because after spending 17 million pounds on Gilardino, we do NOT need another center forward. If we are to replace Shevchenko, it should be with someone more versatile than the 3 above.
Cassano is attractive because of his amazing skill and his young age (still), but his temperament is a major turn-off; I think he is too big of a gamble after the immaturity he demonstrated at Roma. I must admit however that I haven't really followed his progress at Real. Another plus here is that Cassano has shown his ability to excel in Serie A, and that should not be underestimated. That gives him an advantage over Torres, Eto'o and Henry. This advantage isn't huge however, since all would agree that Henry's combination of size, pace, strength and skill is enough to thrive anywhere.
Torres is undeniably talented, but my major concern is whether he can do a good job in Italy; the Spanish game is more free flowing while the Italian game brings huge pressure on and off the pitch, and is heavily dependent on tactics and physique. I don't think Torres is close to being the best option on that list.
Eto'o is the best African striker by far, let alone Cameroonian striker. Not that this has any relevance here, but I happen to be from Cameroon and he is somewhat of a national wonder. About the matter at hand, Eto'o has been excellent at Barca obviously. Some brought up the fact that he was bound to be, given the wealth of talent and creativity behind him (Ronaldinho, Messi, Giuly, Deco, Xavi...) and that's a good point. Note however, that Eto'o has been good for a while; he was a fearsome striker at Mallorca, well before he signed with Barca and he was an absolute terror at the African Cup of Nations in January. The man scores tons of goals because he is good. He would do well in Milan I think, but the concern I have about Torres applies here too.
Henry - skills wise, Henry is the best fit by far. Henry is a most complete footballer on the list and can often be found working hard in midfield. In that respect, he is not unlike Shevchenko. He is faster than all but Eto'o, and is stronger than most. He isn't good in the air, but is a real danger from set pieces (as a shooter). For all his qualities, I wonder whether Henry can stand being on a squad where he isn't a demi-god. One of you brought up the fact that he acts as if Arsenal were his property and chemistry is the only potential problem I foresee with him. I wouldn't be surprised if this concern came to naught, and frankly, Henry has earned the right to believe that Arsenal is his property. I don't think any other club of Arsenal's caliber depends so much on a single player for its success. Not Barca with Ronaldinho, not Manchester with Rooney, not Milan with Sheva, not Real with...Real has nobody
My choice: Thierry Henry.
