Philippe Coutinho has pledged to continue to do his best for Liverpool but refused to commit his future to the club.
The Brazil international was frustrated when his transfer request was rejected in the summer as the club rebuffed three bids from Barcelona.
Since then speculation has continued to encircle the 25-year-old, who captained the side and scored a hat-trick in the 7-0 demolition of Spartak Moscow which booked their place in the knockout stage of the Champions League.
Many fans noticed that, despite scoring three goals, Coutinho barely raised a smile during his celebrations on Wednesday night, with his Catalan suitors reportedly ready to make another approach.
"I am at Liverpool and I always do my best when I have the opportunity to play, respecting the jersey and the supporters," said Coutinho, who has scored nine goals in 13 appearances this season.
"I do not know how the future is going to be. What will happen in January, we will know it in January. I do not know if there will be an offer.
"Last summer there was a job offer in the same way that happens with any employee and I was interested in it. Since I stayed I have played with will and desire.
"Of course a lot happened in the summer but my will is always to play and do the best wherever I am – that has not changed.
"I am here [at Liverpool], we have a lot of games and I try to do my best to help."
Coutinho's hat-trick was his first for the club and he hailed the achievement of making the latter stages of the Champions League as a significant moment.
"It was a special night due to the result and because I had the armband in such an important game playing for a club like Liverpool," he added.
"For sure this is my most important hat-trick. In the Champions League it was my first one, I scored one for Brazil but this was more important."
