Real Madrid manager Santiago Solari has refused to discuss reports regarding the future of Isco.
The 26-year-old has featured for just 78 minutes in total from Solari's six matches at the helm and was left out of the squad entirely for Tuesday's Champions League clash with Roma.
Isco has been linked with a move away from Madrid in January, while other reports have suggested that off-field issues could be behind Solari's reluctance to play him, but the Madrid boss insists that he will not discuss the Spain international's future in public.
"Sincerely, this is a topic that has no more to it. The other day I said that they were specific decisions," Solari told reporters.
"There's no more to it. You will understand that I can't be up to date with all the speculation. I have 24 professionals, we are here to decide. That's it. I do what I consider is the best for each one. They are all important. We are all Real Madrid."
Isco joined Madrid in 2013 and has gone on to make more than 250 appearances for the club across all competitions, scoring 43 goals.
