Suarez agreed a move to the Premier League ahead of the transfer deadline, his opportunities at Camp Nou having become limited under Ernesto Valverde.
And after another week of getting to know his new surroundings, Emery hopes Suarez can become an important part in Arsenal's squad going forward.
'His adaptation to us and also on Sunday in 25 minutes, in the first days with us, is not with good performance, ' said Emery.
"This week he worked Monday with our coaches and also yesterday". He was working with us well today and if tomorrow he is continuing with a good feeling, he can also be with us on Saturday.
"We are strong at home, but I think we need to do better away". Manchester City, Manchester United, Chelsea and Tottenham Hotspur, all won their respective matches, making the title race and the race for the Top 4 even more interesting.
Now, Unai Emery's men must regroup from that and look to win games.
Meanwhile, Mesut Ozil and Aaron Ramsey could be leaving the Emirates stadium at the end of the season so as to help Arsenal raise funds for new signings.
"Yes [we have to win]", he added.
"One month ago we were in the same situation but it's not easy". "I work over anything other criticism can do to me, the work in the present and future can change our way". Denis Suarez may take more time before he gets ready to start 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.
