Crossing & Finishing (Bob Lilley)

Here's a staple crossing and finishing game that Bob runs often (with a bunch of different tweaks):

It's pretty simple, but it creates a lot of game realistic crossing and finishing situations. The GK plays the Target who lays the ball off to a teammate who plays it wide (this is all free). The Wing receives the ball and crosses it. Three players attack (the Target and two other players) and two players defend (play is now live). The Target always stays but never defends. The other two players attack, defend, then rotate out for two new players. The ball is live until it goes in the goal or out of bounds or the defensive team wins it and plays their Target to go the other way.
