Isco says he has no plans to leave Real Madrid and hopes to see out the remaining two years of his contract.
The Spain international has reportedly attracted interest from Serie A and the Premier League as he continues to struggle to hold down a starting spot at Real.
However, speaking to Cadena Cope, the 23-year-old dismissed speculation linking him away from Real: "Go to Juventus? I am very happy at Madrid. I want to see out the two years left on my contract."
There have been reports that Isco and James Rodriguez could be sold by Real this summer.
The pair have come in for criticism this season and Isco was benched for Real's recent 4-0 win over Sevilla after an angry reaction to being substituted in the previous match at Las Palmas.
"It's been a very difficult season but I do not think everything that happens to Real Madrid is the fault of James and me," said Isco.
"After the game against Las Palmas I was angry with myself and I do not think I'm the first player to have done that."
Real are 10 points behind Barcelona in La Liga ahead of the second Clasico of the season at the Nou Camp on Saturday.
"We must redeem ourselves on Saturday against Barcelona after the bad result at the Bernabeu (4-0 defeat)," said Isco. "Winning at the Camp Nou would be a big boost."
