The Red Devils are determined to strengthen their attack ahead of next season. Cunha is one of the top names on their radar.
Talks are already underway with the 25-year-old's representatives and personal terms could be formally finalised in the near future.
Wolves are set to demand his £62.5m release clause but United are optimistic of negotiating a long-term payment plan.
The Red Devils paid more than Joshua Zirkzee's release clause last summer and they could do something similar this time too.
Aside from Cunha, United are pushing to land the signature of Ipswich Town striker Liam Delap amid widespread interest.
Chelsea are also keen on landing the young marksman. It remains to be seen whether United can persuade him to join them.
Cunha has already given the green light for a transfer, having turned down interest from Newcastle United earlier this month.
