The player tucked in just behind the striker could be tagged as someone who has a "licence to roam."
It's a vital role and is seen more and more in football - especially at international level.
Zinedine Zidane has been one of the best players in the world in this position for both Real Madrid and France.
The player drops into the area between the opposition midfield and defence, giving them more time and space on the ball.
It is very difficult to mark this player because they can be playing quite deep one minute and then burst forward to link up with their striker.
They'll be very comfortable on the ball, have great vision and a very quick turn of pace.
They will usually create plenty of chances for team-mates, but also bang in more than a few themselves.
