Strootman has been a United target since the summer with Louis van Gaal known to be a huge admirer of his compatriot.
Reports earlier this month said the Roma star had accepted a switch to Old Trafford, and that now looks to be spot on, with agent Matteo Materazzi revealing everything is almost agreed.
‘Manchester are one step away from Kevin Strootman,’ Materazzi told Rai Sport.
‘The British club will pay €40m (£32million) into the coffers of the Giallorossi.’
Chelsea were previously linked with the midfielder, but were not willing to make a bid until the summer.
