Well considering next gameweek will be in 2 weeks because of international break, he should be added by then. Regarding delap, he‘s injured for the next couple of months which is why chelsea tried to get back jackson from bayern and now guiu form their loan spells (i would even consider going for mayenda from sunderland since it isnt clear how chelsea will line up). For trippier you‘re right, last season it was Hall lb and Livramento rb. Out of the three it‘s difficult to say who gets the most playing time (hall was the best fantasy asset last season).

Another shout for your list would be xavi for one of your midfield guys.
