Cana is set to make his return from suspension this weekend.
He is excited by the prospect of facing Arsenal, having missed out on the 2-0 defeat to the Gunners' rivals Tottenham last time out.
Cana told the club's official website: "It was very hard for me to watch my own team-mates from the sidelines. I could not do anything. Especially for myself, it is very frustrating.
"But I did not have a choice and it was important for me to be there with them and support them even though I could not play."
