Basics?You cant allow a team like Liverpool to run at you unchallenged.
You cant allow players like Salah and Jota into the box repeatedly, and allow them into their strongest foot.
You cant have Goldson marking VVD at setpieces.
You cant expect to get anything from a game when you cant string 5 passes together, because you are being outworked by an already superior opposition.

Stopping Salah from coming in the box and marking Virgil Van Dyke?
Aye school boy stuff really.
