The Rovers are currently rooted to the bottom of the Barclays Premier League table with just a point after four games.
They will welcome a rejuvenated and strengthened Gunners side who are on the back of a win against Swansea at the Emirates last week.
Rochina, who scored a stunning goal in Blackburn's 1-1 draw against Fulham last week, believes his side can upset Arsenal.
"Fulham are a good team and I think it was a good point," the Spanish striker was quoted as saying in the Lancashire Telegraph
"It was very important. The game wasn't at home, it was a difficult game.
"Arsenal is a good game but I think we must work hard and I think we can win the game. They are a great team but we have many good players and a good team. I think we can win.
"Next weekend I will try for that, and the other players the same."
