It's more than just not having Lenton there,although your points are valid There have been countless times where he's had space and the opportunity to drive forward with the ball,but hesitates,slows down and pass the ball back or sidewards...He no longer has Lennon to create space for him by distracting defenders. Plus nowadays it seems like defences are better drilled at keeping two solid rows of four between them and the ball the whole time - especially when they play us.
