You are dumber then I thought, a winger who can cut in with his preferred foot is alot less predictable then one who can just go outside, since most wingers can cross fairly decently with their weaker foot, but rarely do any cut in and shoot with it.
I don't know if you wached sassuolo this season but for example in the Napoli game berardi was completely shut down in the right wing because they knew that berardi was going to cut to the leftside so they used their leftback to cover the right side of berardi and they used their midfield to cover the left side of berardi and the midfield was doing the most work because berardi was always trying to cut in and getting caught or tackled. was was incredibly predictable.
berardi is more of a finisher than a pacy winger so him at the leftwing would do a similar job to griezmann at sociedad or reus at Dortmund where he just picks up the passes and finishes the chances. on the leftwing he can cut in with his right and then cut again on his left which makes him very unpredictable or he can cross with his left.
The context you are taking about is if you have a winger like robben or cerci where they focus more on assists and runs then scoring goals.
