The Red Devils have already splashed around £56million on new players since the end of last term, with England left-back Luke Shaw and Spanish midfielder Ander Herrera having been brought in from Southampton and Athletic Bilbao respectively.
However, those signings could prove only the beginning of Van Gaal’s recruitment drive, with United executive vice-chairman Ed Woodward confirming the club’s willingness to spend in the market.
“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.”
