Nooooo, Alves has to remain as RB, Adriano is much more of a winger than Alves will ever be... Alves is awesome as RB because his offensive contribution comes from behind of our forward line, making him the extra player we need to deploy tiki-taka football, also his runs from behind surprise opposition's defense and enables our players to pass through-balls in his direction... On the other hand Adriano is always willing to go one on one against his defender and cross the ball, more in the vein of a traditional winger, Adriano is not that interested in linking up and making one-two's like Alves, he is determined to beat his marker and cross the ball...
The above was quite evident in the match against Valencia, Alves rarely took on his man and was working with our horizontal play in mind, while Adriano came all guns blazing and beat his man a few times...
