Alcacer's sale has been met with a backlash from Los Che fans.
"For me I'd have no problem returning to live in Valencia," he explained.
"People are free to express themselves as they want and I have to respect that. I wish Valencia the best and hope they return to the top level. I'm only thinking about the future now.
"At Valencia they've not been doing things well for a few years and they've not achieved results.
"If they do things well, they'd be close to Barça and Madrid. I wish them the best and hope they continue improving."
