Schalke general manager Horst Heldt insists the German club has still had no firm offer from Arsenal for Julian Draxler.
The Bundesliga side want £37m for the 20-year-old Germany attacking midfielder and are not keen on a player-plus-cash deal.
Gunners boss Arsene Wenger appeared to concur with Heldt, insisting after his side's FA Cup win over Coventry on Friday night that the story linking them with Draxler was "an illusion."
Speaking after Schalke's Bundesliga win at Hamburg on Sunday, Heldt suggested any questions over Draxler should be directed at the Arsenal manager.
"You should ask Mr Wenger, call him. There's no contact with Arsenal or any other club," said Heldt.
"I cannot exclude the option we will sign Cristiano Ronaldo. I don't need to talk about this.
"I understand why you are asking the question but all the topics you mention need to be addressed in London."
Wenger says he has more than enough wingers at the club and insists that he will not be signing Draxler.
"There is nothing happening, honestly no," Wenger said after the win over Coventry.
"We don't need to take players on the flanks - we have 17 players on the flanks."
