Lionel Messi will end his career at Barcelona, Chelsea manager Jose Mourinho believes.
Ipswich have signed striker Chris Wood on loan from Leicester until the end of the season.
The Swiss is the frontrunner for the vacant position following the dismissal of Michael Wiesinger on Monday night, but Nurnberg's director of sport Martin Bader has refuted a claim by the Bild newspaper that he had been appointed.
"Nothing is definite with Mr Gross," said Bader to Sport1. "We're currently considering several options."
Gross is currently out of work since being dismissed by Young Boys Bern in April 2012 while he would be no stranger to the Bundesliga having coach Stuttgart between December 2009 and October 2010.
Whoever is appointed will have the clear task of keeping the club in the Bundesliga, where they have established themselves recently.
"Nurnberg have proven in recent years that we belong in the Bundesliga," Bader said. "I think after finishing sixth, 10th and 10th in the past three seasons, we should be confident enough to say that.
"Furthermore, we have managed to develop the team constantly, improving step by step, and we want to carry on this path with our new coach."
In the meantime, youth-team coach Roger Prinzen is leading the first team's training with a new full-time coach expected to be installed during the two-week break for internationals.
