"There is no fixed budget. Financially we are extremely strong, we have funds available," Woodward told MUTV.
"Louis is the boss and is assessing what's going on but we have been in dialogue for some time about targets so there is a lot of work going on behind the scenes... we're continuing to move forward on some of those targets... so watch this space.
"The time he (Van Gaal) spends here as well (in America) he'll be able to assess more what he's got and continue to tweak the decisions if we need to.
"We want to do what it takes to win the title."
"I've experienced a lot of conversations with agents and players and we are still a huge attraction to top football stars around the world - there is no doubt about that.
"We've already invested in two new fantastic players."
As many as ten players have been linked with moves away from Old Trafford. When asked if it were true, Woodward responded:
"Yes, I think so.
"The manager makes that decision and a few players have already gone and there may well be a few others that go.
"It's also worth commenting that we're not in Europe this year (so) there's less games, maybe the manager takes the view that he wants a tighter squad to bed in.
"If you do the analysis over last year, Liverpool performed extremely well with a smaller number of players but that's a decision for the manager."
