With the addition of Kagawa, one would assume that SAF could be swaying towards playing a 4-2-3-1 for the majority of next season.
Now, a 4-2-3-1 doesn't really consists of out and out wingers, i.e. Valencia, it consists of attacking midfielders with the capability of cutting in and influencing the game from the middle, i.e David Silva. Due to Valencia's inability to use his left foot, I don't think this formation would suit him if he was to play right midfield.
In a 4-2-3-1, most of the time, the width comes from the full backs who constantly get forward and deliver crosses. This is why I feel Valencia would be best suited as a right back.
In my opinion, Valencia has all the attributes to become a great right back. He's got great stamina, box to box, strong, fast, decent at defending and we all know how good his crossing is.
The formation would look like this:

Subs: Lindegaard - Evans - Rafael - Cleverley - Young - Welbeck - Hernandez
As you can see, the two full backs, Evra and Valencia give us the width while Nani and ? cut in from the flank and link up with Kagawa and Rooney.
In the right attacking midfield(RAM) postion I have put a question mark. Personally, I would like to see a left footed play occupying that spot. Someone who can cut in and either shoot or play through balls over the top to Rooney or whoevers playing upfront. Maybe J.Rodriguez, Dembele, Gaitan or even try Anderson there?
I've also put a question mark in the midfield area next to Carrick. In my opinion, i'd like to see an all rounded box-to-box midfielder that can also play Carrick's role if he was to get injured. Maybe Strootman, Martinez, M'Villa?
What do you think guys?
