haha, this is a very common tactic being used by the striker to fool the fullbacks..try playing fifa or pes..this is always a great chance for the striker to come to the middle from the right/left flank..

the only the fullbacks can do is shout for the offside jz to change the linesman mind and at the same time run towards the striker to close him down..

usually the striker will sent the ball to the middle instead of shooting because he hold the ball at the same time, but the gk is there..so he will search for his teammate..let the center backs and the other fullback prevent the ball from reaching the ongoing midfielder and strikers into the box..

thats all u can do, jz close him down..if you are faster than him..maybe u can make a sliding challenge from behind..but make sure you tackle the ball, not his legs! sometimes u might get a foul..but if inside the penalty box..youll be damned..LOL
