The 20-year-old midfielder has one year remainnig on his contract but wants regular first team football next season.
“My priority is to stay here, but Porto is an excellent option if I leave Liverpool," he admitted. "I know there’s negotiations.
“Porto are the best club in Portugal and they have faith in their youngsters. They also have a coach I like working with.
“I will only renew with Liverpool if I’m guaranteed I’ll play regularly.
“The option is clear: if I don’t renew, let me leave. I think Liverpool thinks the same.
“They won’t let me leave on a free in a year if I don’t renew. Let’s see what happens.”
