But the shot-stopper has decided against a transfer and will stick with United at least until the end of the season.
It is claimed Romero could be moved on in the summer when United have had a chance to fully assess 20-year-old keeper Joel Pereira, who is currently on loan at Belenenses.
Discussing Romero’s future before United’s draw with Stoke today, Mourinho said: "I cannot have a better goalkeeper than David (De Gea), I cannot have a better replacement than Sergio. I cannot have a better professional than Sergio.
"I want them both to stay. So, if there is something true in relation to Boca, I will try to stop it because I want Sergio to stay."
