Sir Alex Ferguson: "I think he is a good passer of the ball and has good vision in his passing too.
"I think the goal he made last week for (Shinji) Kagawa against Tottenham is evidence of his passing ability. I am quite happy with what he is doing now.
"The refreshing thing for me is, he has actually not had any pre-season games, which is quite remarkable, having seven goals from seven games.
"I am quite pleased about that and I think his fitness will improve even more.
"I would love that to happen.
"In my experience of where we are the moment I think you need two strikers who will get you 20 goals. You get that, then you definitely have a live chance.
"Both (van Persie and Demba Ba) have good scoring records," Ferguson said. "They rested Ba on Thursday (their 3-0 Europa League win over Bordeaux) and played (Shola) Ameobi.
"I don't know what the combination will be. There is talk about including Ameobi in the team for Sunday. But, either or - Ba and Ameobi are strong, aggressive players and Cisse has scored some fantastic goals for them.
"We are aware of their strengths and (Hatem) Ben Arfa from midfield is an excellent player."
