The Brazilian attacker's representative confirmed that Mourinho is an avid fan of his client, but stated that the player is not interested in a new challenge just yet
The 19-year-old sensation has emerged as one of the hottest prospects in South America, with Chelsea, Inter and Real Madrid all vying for his services.
It was suggested that Lucas could be the at the centre of one of this summer's long-running transfer sagas, but according to his representative, all offers will be quickly rebuffed.
"Inter made me an offer of €18m for Lucas, but I did not even waste my time with that because the player has already said that he does not want to leave Sao Paulo," Wagner Ribeiro told UOL Esporte.
Jose Mourinho is believed to be a fan of the young attacking midfielder, with the Portuguese coach having flown to Hamburg last week to watch the player in action for Brazil during a friendly against Denmark. And the agent admitted that the Real Madrid trainer is continually tracking his client's progress.
"Mourinho watches all of Lucas' games, whether it is live or on tape," Ribeiro added.
Lucas, who arrived at Sao Paulo at the age of 13, has a buy-out clause worth €80m in his contract.
