This weekend we will find out who will make the final - the semi-finals see Chelsea play Manchester City on Saturday (live on BBC One at 17:30 BST) before Leicester face Southampton on Sunday.
Lawro's guest predictor this week is Soccer AM legend Tubes, who has been speaking to players to get their previously unheard stories around the FA Cup as part of his Lifting the Lid series with the Football Association.
Tubes is a Chelsea fan, and there was never any chance he would support anyone else.
"I'm from a big Chelsea family," he told BBC Sport.
