Rooney has not scored in open play for United since March 30.
“Everyone knows what happened over the last couple of weeks beforehand but Wayne’s come back and he’s looking sharp,” said Ferdinand to the Mirror. “He didn’t score in our last game but he looked sharp and set up a good number of chances for other people.
“It’s only a matter of time before he scores and then goes on one of those runs where he scores loads of goals. Just having him back around the place in a good mood is fantastic. He’s a great lad to have around and long may it continue.
“Arsenal are a good team but I’m concentrating more on what we’ve got in our dressing-room. I’m confident in our team and the individuals as a collective that we can go out there and beat any team and I’ll be looking to do that on Monday.”
