Davide Santon is better then maicon
Santon ends up being better than maicon but you will have to develop him for a few years. At the start of the game maicon is one of the best rb's. Though i found both of them to be very hard to buy. Ended up buying Srna. He was amazing in 09, hope he performs as well now also. already have rafael for the long run.
Also who is better in fm2010, akinfeev, asenjo or lloris??
