The Boateng one is just sheer laziness and poor body positioning, not bothering to stay on his toes. He probably half gave up at that point, it's easy to stand and be mesmerised with a little test tube goblin dazzling you.
All these vids above - that's why good defenders are so cherished, they (and goalkeepers) can all be embarrassed as there are so many skillful players, everyone gets made to look stupid from time to time, but you don't see any overall level of defending just looking at few minutes of highlight videos. The likes of Messi, Ronaldinho, even far less established players like Robinho, Denilson, Quaresma and others with quick feet and skills have all destroyed defenders 1, 2 or 3 at a time at some point.
tl;dr vids mean fuck all.
