It's quite understated how difficult a chance that is to take. Some may say "Oh he only has to touch it" that isn't true, the balance and execution of that is not easy at all. If we are talking the whole thing, firstly the chest touch has be 100% immaculate so that 1. The ball doesn't get away from him and 2. The finish is quality because he has to stay balanced, but execute perfectly whilst putting enough purchase on it to not only nick it over the keeper, but to have enough pace to make it enter the goal before the defender can deal with it. One of my favorite Costa goals this one.
