Porto defender Rolando is being chased by Juventus and Inter Milan, according to his agent.
The 25-year-old Portugal stopper has produced some impressive performances since his arrival at Porto in 2008 and was linked with a move during the January transfer window.
His agent Peppino Tirri claims Premier League sides Manchester United and Liverpool watched him during the Portugal versus Argentina friendly in midweek and says Juve and Inter have already made approaches for his services.
Tirri told calciomercato.it: "Yesterday there were observers to follow him (in the friendly Portugal-Argentina) from many clubs including Inter Milan, Juventus, Manchester United and Liverpool.
"There are possibilities he arrives in Italy, we will work from here to June but there have been approaches with Juventus and Inter.
"The player's rating is very high. €15million? Even a little more."
