Guti's former club Madrid finally brought to an end Barcelona's dominance in Spain last season when they won the La Liga title for the first time since 2008.
In a bid to continue that success, Madrid are looking to strengthen their squad this summer and have been linked with a number of players.
One of them has been David Silva and Guti believes the Spain international would be a perfect fit in Jose Mourinho's team.
"There would be no better signing. In his position he is among the best. He would be a very good addition to a squad which is already excessively good," Guti told AS.
There has also been speculation about Tottenham playmaker Luka Modric and a possible switch to the Bernabeu.
Guti said of the Croatian: "He's very talented but I don't think he's at the same level as Silva. He's shown that he is very good at Tottenham and Croatia when you see flashes of the quality in his boots."
Guti himself has been without a club since leaving Turkish side Besiktas in November.
However, the 35-year-old midfielder has no intention of hanging up his boots just yet and hopes to have finalised where he will be plying his trade next season in the next couple of weeks. .
He said: "In 10 or 15 days everything should be closed. I hope then to be able to announce that I'm going to continue playing for another year.
"I want to play for another two years, although things aren't as easy as they were before, I've had six months without playing...We'll see how I feel this year."
Guti, who was linked with a move to newly-promoted Barclays Premier League club West Ham recently, also feels he does not need to prove anything to prospective suitors.
The ex-Spain international, who spent 16 years at Madrid before moving to Turkey in 2010, said: "At this stage of the film I'm not going to go for trials. If somebody wants me, they must trust in me 100%."
