Alberto Moreno believes he has been 'mistreated' by Jurgen Klopp at Liverpool and is weighing up a return to Spain.
The full-back, who is currently recovering from a back injury, is out of contract in the summer and has made just two Premier League appearances this term.
The 26-year-old has fallen behind Andy Robertson in the pecking order at Anfield and says he is "tired of the cold" in England.
"I do not feel good, that is the truth," Moreno told Cadena Ser.
"I hurt myself giving everything for this team and I think that when I came back from injury, I deserved an opportunity.
"The situation is normal for a lot of players but simply, I did not like the way he (Jurgen Klopp) has treated me, you can say that.
"Moving back to Spain is something I have thought about, I am tired of the cold here but I do not know about interests from other clubs.
"I am in my fifth year here, there is no agreement on a renewal and in January, I am free to listen to any offer."
