Sevilla midfielder Ivan Rakitic is adamant they will defeat Manchester United tomorrow night.
Sevilla host the second-leg of their Europa League quarterfinal. The aggregate score is locked at 1-1.
"These people don't know what awaits them on Thursday," Rakitic told AS.
"It is a team with a lot of experience and many millions, but United does not know what Ramn Sanchez-Pizjun is like packed.
"I know from when I was at Barcelona that players from other teams sing the Sevilla anthem on the pitch.
"It's unique. What our fans have created is very impressive."
He also stated David de Gea and Casemiro will be nervous having played at the Ramn Sanchez-Pizjun.
"De Gea or Casemiro, who have played here, will surely explain to them that this is something else.
"You get anywhere and they say that this is Sevilla's competition.
"They are going to have to suffer, I cannot guarantee that we will qualify but we are going to leave everything on the field."
