Lucas aims to help Liverpool into the Champions League – and earn a new contract.
But Liverpool’s long-serving Brazilian midfielder admits talks are on hold until the end of the season.
And with just one year left on his deal at Anfield, after joining from Gremio in 2007, Lucas knows he could yet be sold.
He was recalled for Reds’ 1-0 win at West Brom as Jurgen Klopp’s men climbed to third.
Lucas said: “I want to finish the season on a high. The opportunity I have been given I think I have helped and I hope I can help in the next five games.
“I have been here long enough and if the time comes for me to go somewhere else I think I will leave with the feeling that I did everything I could.
“I have got one more year left after this but I think I need to just concentrate on the next five games. I don’t really know what will happen.
“The last few games I have played I feel very good. I have played centre-back and midfield, so I give some options to the manager and when he needs me I always try to deliver.

Jurgen Klopp speaks after West Bromwich Albion 0-1 Liverpool
“There is no doubt about my commitment to Liverpool. I just need to wait until the end of the season, work hard and make a decision together with the club.
“I feel I have many years that I can still play at the top level. I need to analyse and see what is best for me and the club and then I am sure we will make a decision together.”
