Tiago has described Diego Simeone as "like a god" ahead of this weekend's Champions League final in Lisbon.
Atletico Madrid, who were crowned La Liga champions last weekend, will face rivals Real Madrid in the final tomorrow.
"For us, for all the club, he is like a god. He arrived at the club and he changed everything," Sky Sports News quotes the midfielder as saying.
"What he says to us comes true and we would follow him. If he asked us to go and jump off a bridge, we would jump.
"He knows so much about football, we follow him and we are very proud to have him as our coach."
Simeone took charge of the club in 2011, and has won the Europa League, Super Cup and Copa del Rey since taking up the role.
