Heading into a week that ends with a north London derby, it was vital that we build up momentum again after the international break.
We did that with a hard-fought win against Bournemouth on Sunday, and Sokratis - who was in fine form at the Vitality Stadium - feels that we are developing well as a team.
"We are around 70-80 per cent [of our potential]," the Greek defender said. "We need to improve sometimes to not lose the ball or when we have the ball to finish the action and score.
"That is the difference, we need to improve and we know this. We work every day and I am happy that I am part of a team that works very good together.
"We have confidence [we can get into the top four] but it is not easy. Next week is very important, it is good that we didn't lose points because we go full of confidence and we will see.
"Of course we need to improve, of course we would like to put Arsenal in the top teams in the Premier League – we try every day for this.
"It will be difficult against Tottenham. You have a lot of games, everything gets changed – a lot of players. It is difficult but what can I say? For now we are not bad, we are good.
"It will be a very important game - but I don't think it is a game that can give you the Champions League. For example, if we win against Tottenham and lose some other games, it is the same thing.
"For me, it is very important that in every game we look different, we go for the win in every game and in the end we will see how it is going. But of course Tottenham is a very important game."
