Borussia Dortmund striker Robert Lewandowski reportedly tops Ferguson's wish-list, while a move for Tottenham star Gareth Bale and a shock return to Old Trafford for Cristiano Ronaldo have also been mooted.
"Everything is in place for a big signing. I think that the Glazers have been great. Whenever I have asked, they have delivered. If I ask to go for a certain player, I think they will do that," Ferguson told The Daily Mirror. "When I spoke about value in the market a while back, I was talking about young, developing players. Maybe there has been a wind of change and I could go for a really top player now. We have a nucleus of young players here, but we may spend something.
"When it’s a top player, it doesn’t matter what position they play in. I will bring them in if they add to the team. Last season we had [Javier] Hernandez, [Danny] Welbeck and [Wayne] Rooney and we still went out and bought Robin van Persie.”
The purchase of van Persie went against the policy of a "nucleus of young players" at Old Trafford, and Ferguson admitted the deal to bring the striker from Arsenal was heavily discussed following similar, but less successful moves in the past.
"Van Persie’s age was certainly an issue because it has not always worked when we have bought older players," Ferguson said. "David Gill said to me after we bought Dimitar Berbatov [from Tottenham for 30 million pounds] that we had to be careful when signing older players, but van Persie was different. He was phenomenal for Arsenal last season and so I was confident it would work.”
