Manchester United target James Rodriguez has remained coy on his future amid further interest in him.
United scouts have been present at seven Porto games this season to monitor the winger.
Rodriguez, who has previously stated how flattered he was regarding United's interest, is available for around £30m.
Sir Alex Ferguson was recently asked about the 21-year-old and he admitted Porto will push for as much as possible before a deal can be agreed.
The Colombia international, however, remains tight-lipped over his future.
"We must be calm and quiet," he said. "Rumours and are to be taken with caution. When you are focused on your work it is normal things go well.
"But I think it is premature to think about my future. For now, I prefer to live in the present."
