Draxler is a good addition to the squad, Cazorla is 29 and Arteta, Rosicky, and Flamini are all in their 30's. It's likely Ramsey, Wilshere, Ozil, Zelalem are the future, and Draxler is a nice fit between Zelalem and the other 3. This is assuming we get him.
Going into the 5th round (16 teams) there will likely be:
Liverpool, Cardiff, Southampton, Swansea, Sunderland, Palace, Man City, Everton, Fulham, and Chelsea (unless Stoke do us all a favour).
Of that list I imagine only 3 maybe 4 teams giving us trouble, assuming the rest of the opponents left are non EPL.
Bottom line we should be targetting the FA Cup as a real option now, 4 matches to win.
