Saul Niguez has dismissed speculation about a potential move from Atletico Madrid to Manchester United.

Jose Mourinho reportedly wants to sign the 21-year-old Saul next summer.

"As long as (Diego) Simeone stays here, I'll be here," said Saul. 

Simeone handed Saul, a youth product of Atletico, his first-team debut at the age of 17 in March 2012 and the player made his first La Liga appearance 13 months later.

"When a coach shows you such trust and gives you so much confidence, it's key," Saul said. "When you play one or two games where you are not at your best but he still plays you, in the end you die for him because you feel you owe it to him.

"The calmness that he transmits to me makes me be who I am today on the pitch.

"It took me a long time to gain his confidence but now that I have it, I'm going to continue to work for him, giving my all."
