you need a breaker to break the flow of the ball from the mid, usually the center back or def midfielder. Just like everyone said here, the strategy of defending is taking a team not an individual. But if the situation is like you draw, your center back is making a mistake, he should approach the the guy with the ball so both you and the right back can follow up to set the striker for an offside. One note that you should always remember: you should never let a playmaker approaching freely to your defensive area, your picture really annoys me because i dont see a midfielder there to guard the area lol..
