Muriel was linked with the Reds during the transfer window.
"Muriel is a player of talent and potential, so I think it is normal that big clubs should follow him carefully," agent Helmut Wennin told calcionews24.
"However, I have had no contact with any English clubs regarding the future of Luis. I haven't had official contact with Italian sides either, but I don't know if the Pozzo family has discussed the situation.
"Udinese and the Pozzo family represent a fundamental step in Muriel's career and were very important in his growth process as a player and a man.
"Now Luis is focused on the current season, as he wants to do well in order to earn his spot in the Colombia squad.
"He has an excellent rapport with Francesco Guidolin and respects all his decisions for the good of the team. He knows that he is an important player for the club and has faith in his own capabilities."
