The former England coach still has extensive contacts in the country where he managed Porto and Sporting Lisbon, and Benfica youngster Miguel is the latest name on his hit-list.
It is understood that talks have already begun between the two clubs, with Benfica demanding a fee in the region of ‚é¼4 million.
An impressive performer at Under-21 level, Miguel is a midfielder with a big future.
The Lisbon-born 22-year-old has formerly played for E.Amadora, and is believed to be Robson's chief target and not the similarly named Pedro Miguel 'Pepa'.
Miguel is rated as one of the brightest talents in a country now looking for new heroes with the old guard poised to stand down after their World Cup disappointment.
Luis Miguel Brito Garcia Monteiro, to give him his full name, scored six goals in 27 games last term.
The Portuguese youngsters swept their English counterparts aside in Switzerland's summer tournament, and the player performed well against David Platt's men in a friendly match at Stoke's Britannia Stadium.
Further talks are expected to take place this week and contacts close to the player claim he is happy to consider a new adventure in England, particularly as international team-mate Hugo Viana is already on Tyneside.
Benfica played down the reports insisting they are keen to keep Miguel at the club.
"We are not aware of any contact from Newcastle about Miguel," said a Benfica spokesman.
Meanwhile, another Benfica man, Simao Sabrosa, has refused to discuss the possibility that he will be heading for St James' Park.
"I have already said I do not speak about these things," he insisted.
"I do not have knowledge of anything, nor can I say anything.
"I only know that I am a Benfica player."
Viana has already joined The Magpies from Sporting Lisbon, but it would seem that Robson, who is waiting to tie up a move for Ipswich defender Titus Bramble, still has other irons in the fire.
