Sokratis has missed our last two matches against Cardiff City and Manchester City after suffering an ankle injury during our FA Cup defeat to Manchester United at the Emirates Stadium on 25th January.
"We can have better balance [in performances] when we prepare by thinking it's going to be very hard", Emery said.
Unai Emery's side sit sixth on the back of Sunday's 3-1 loss away to last season's champs, Manchester City, a point below Manchester United and three behind fourth-placed Chelsea.
A 2-1 win at Bournemouth on November 25 was the last time Emery's side took three points on the road, but Huddersfield looks the flawless opponents after losing 11 of their past 12 league games.
That is reportedly to do with the need to fall into line with Premier League guidelines on transfer fees and wage expenditure to do with Financial Fair Play, leaving Emery facing the prospect of offloading current players to fund new arrivals.More news: To-Play Titanfall Battle Royale Game, Apex Legends, Will Release Tomorrow
"Yes [we have to win]", he added.
"How we are doing at home and away, we are with the possibility and the opportunity of (finishing in) the top four". Respect for the opposition is one of his guiding principles but it was also easy to discern the message for his team. We started very well away, changing our mentality, but now we need to recover this confidence, to recover this performance and the next opportunity is against Huddersfield. I spoke with the players [and told them] we need to think this match is very important for us and every player needs to be ready, be focused and be thinking we need to win this match.
Arsenal travel to Huddersfield Town on Saturday afternoon. After that, we know we can win.
"For us as well, away games have been a challenge and each match is a new challenge. We need to be confident and take more confidence and continue working".
"But the problem is, they can't get the players available". I want to do the same on Saturday against Huddersfield.
