According to the Monaco forum, old slight injury contracted when he was in Madrid until the end of December...
The fans on this forum are scared that he played his last game before going to... chelsea.
May be same kind of (fake) injury that Sturridge "suffered" before going to Liverpool.
That says that he is not really injured but feeled some pain.
I know nothing reliable at all, but worth a read if you understand some french http://asmforum.fr/topic/38069-radamel-falcao/page-158
They also think he is quite shit/average on that Monaco forum.... I don't think I want him as our striker.
"Tu prends le Falcao de Monaco en oubliant le passé, c'est loin d'être un crack. Vitesse banale, accélération très moyenne, élimination très faible, détente inexistante, remise maladroite, puissance de frappe très moyenne. A côté de ça, il est précis face au but (bon il y a des loupés mais qui n'en fait pas?), son ratio de but est bon malgré ses faibles occasions."
Translate freely: he is very, very average and far from being a crack. His goal ratio might still be ok but there are the weak performances.
Also: they say repeatedly on that forum he can score a goal sometimes but adds nothing in link-up or general play (no acceleration, average speed, no tracking back, ....). He is precise when placed in front of the goal.
I still believe this would be Torres 2.0. Also money-wise. No go for me.
