If a team doubles up on both Bale and Lennon, Modric will tear them a new one with the space it will allow him to pass.
Lennon's big thing is he stays wide, and gives the midfield another option for the counter attack.
Not to mention his often-underrated defensive shift.
Although he has little defensive talent per se, he uses his pace to make it very difficult for the opposition to build down our right flank.
