I'm in Brasil at the moment, and was fortunate enough to catch the Taca Libertadores match live between Atletico and Newell's Old Boys - Bernard ran the show completely in the first half. Pass/move, excellent passing ability and vision, and beat his fullback for pace on more than one occasion. He is very much a wide-playmaker a la Nasri (when he was really good), and Wenger loves those kinds of players, so I can see us being interested. Scored a good goal too from a choice Ronaldinho pass. Cazorla behind the striker, with Bernard moving through the channels from the left sounds very good to me, especially if there isn't an oaf up front who put away his chances.
And Gilberto has still got it. He's slower than a plant on valium, but he won all sorts of aerial balls and stopped a fair share of attacks.
