I think Henry is into a great shape and has a great co-operation with his current team formation/playmates. He is a great forward anyway, excellent purchase for any club, but really quite unlikebly to come to Juvetus and even Seria A.
If he goes to another club it will be for sure a club of Nike, because he has this contract still running and it is keeping Ballack in place, imagine about Henry...HE is currently running equal spot time to Ronaldinho, which leads to one team... anti ADIDAS spot time team... anti Real Madrid!!!
Of course that includes Juventus as well, he is one of Nike-teams and it is a top selling one, but due to the previous experience and this years CL end it will be most probably Barcelona or Arsenal - one of the winners, both playing with Nike...
But I do honestly believe that unless they attrack him with a crazy deal and amazing salary (140.000 Pound/Weekly were mentioned in the forum, for me it will not be more than 4 years contract) he will sign with Arsenal until the end of his carreer. Important factor is Arsenal winning CL this year and getting money for his contract, not only by CL but also by Nike

(seriously!!!). So it is a tie situation - either Barcelona create a DreamTeam AntiREAL, either the guy stays in Arsenal. There are no other clubs playing with Nike for exchange or Transfer, Real will be very unlikely due to Adidas connection (Inter? - Adriano? - NOOOO! ) he will not be in Italy almost certainly.
If he joins Juve I will be glad, but not on the expense on much needed players now, which we currently need - ( AMF and CMF - a more creative and young one to substitute Even Vieira/Emerson when needed). If we get what we need and Henry it will be more like Juve- Dream team and we could swap a record breaking deal with Ronaldinho, but the world is getting unrealistic...

So I hope we concentrate over our young tallanted buy and Henry goes to Barcelona to create a Dream team and we BEAT them on the FINAL of CL next year, with a winning goal of DEL PIERO with ADIDAS in the 90th minute...
