Old Trafford manager Sir Alex Ferguson and Anfield boss Kenny Dalglish are both known to want to sign a centre-back this summer to reinforce their respective squads.
Rolando's agent, Peppino Tirri, claims that his client is attracting interest as a result and he expects progress at the end of April.
Tirri believes the 25-year-old would cost around 15million euros (£13.2million) and it remains to be seen if North West enemies United and Liverpool enter a bidding war.
Inter Milan and Juventus have also been credited with interest, but Tirri told Notiziariosportivo.com: "There is also Manchester United and Liverpool following the player.
"I think something could move towards the end of the month. Now the clubs are focused on the championship and the Champions League."
