Hopefully both when Pogba is back, otherwise it depends on the game and the available attackers starting being Zakaria the more conservative defensive option.
Zakaria can only be a tactical player when we want to put more muscle in midfield, he just keep screwing up our build up play even during preseason games
Paredes will be useful and a loan + option clears the risk of 'Ramsey/Arthur situation', leaving us budget to strengthen the squad during mid season
