So far, I've liked what I've seen from Rossi. But I've liked Kun more.
We pay more for Aguero but we would also get more.
1. He's been good for several seasons, in an instable team.
2. He's argentinian, which might help partnership with Messi. They would practice together in NT and perhaps in the future even play together.
3. As people has mentioned, he's played better at NT, which is a sign that he can adapt better than Rossi.
I just feel better thinking about recruiting him than I do about Rossi, even though Rossi wouldn't be bad news at all for me.
Whoever they choose, I hope they will be in good form and help our team.
