Nicolai Muller has claimed he knows nothing of a transfer to Bayer Leverkusen, despite speculation he is set to move to the BayArena.
Reports are suggesting Muller is the Bundesliga club's preferred option to replace Andre Schurrle if he, as expected, joins Chelsea this summer.
But the Mainz forward, who scored eight goals in the Bundesliga this season, insists he is not looking to leave the Coface Arena.
He said: "I am under contract with FSV Mainz 05 and I feel happy about this.
"I have just read about a potential interest in me from Bayer Leverkusen but I am not aware of anything concrete."
Meanwhile, Leverkusen have confirmed that Junior Fernandez will spend 2013/14 with Dinamo Zagreb.
The Chilean striker managed just six appearances after his move from Universidad last summer and he will move to the Maksimir to get first-team football.
General manager Rudi Voller said: "We are still very much aware of his general talent and have started to work out this loan deal with Dinamo Zagreb to help his progress as a player.
"It will be a great opportunity for him to mature as a footballer and to then return as a stronger player to our club."
In an interview with Uruguayan radio station Sport 890, Suarez also insisted he is not prepared to put up with the criticism he has faced in England any longer.
He says his treatment by the media has affected his family and could force him to continue his career elsewhere.
Suarez said he had talked to Reds coach Brendan Rodgers and the Northern Irishman knew what he wanted.
The 26-year-old has courted controversy since his arrival from Ajax, facing repeated accusations of diving, and serving a ban for racially abusing Manchester United's Patrice Evra and another for biting Chelsea's Branislav Ivanovic.
Suarez said: "I'm happy at Liverpool, I'm happy because of the fans. I made a mistake, I'm human, but they've talked about me in ways they shouldn't have.
"My family have suffered and things got out of hand. My daughter and my wife have suffered. I'm not prepared to continue to put up with the English press.
"I love Liverpool, but if there is a chance of playing somewhere else... I suffered too much as a kid to get where I am to be attacked unfairly by the English press. They haven't appreciated me as a player, they've just judged my attitude."
Asked about Madrid, he said: "I've talked to my agent, there's nothing concrete. To say no to Madrid would always be difficult and more so with the team they have.
"I have a contract with Liverpool, but it would be very difficult to say no to Real Madrid. There are a lot of rumours in the transfer period, but you never know until firm offers are made."
He added: "I've talked to the coach (Rodgers), and he knows what I want. He was a player. Some of the players understand my situation - enough said."
The striker has established himself as one of Europe's leading players since moving to Anfield in 2011, but his indiscipline has meant the club have had to cope without him for long periods.
He will miss the first six games of next season following his 10-match ban for biting Ivanovic, having been banned for eight matches for abusing Evra.
Madrid are currently looking for a new manager, with Jose Mourinho leaving at the end of the Primera Division season.
