The 22-year old midfielder has been used just once off the bench in the Premier League so far this season but has put in full shifts in the previous league cup wins over Exeter City and Birghton.
Tomorrow night, the Reds are away at Britannia Stadium and Spearing is intent on performing at his best for both the good of the club and his own chances of breaking back into Dalglish's first team.
"It has been a mixed season for me so far," Spearing said.
"With the new players that have come in I haven't had as many chances as I would have liked, but at the end of the day it's down to me to keep working hard every day in training and show the manager I deserve a chance when the time comes.
"I have to look at the positive side of things. The boss has put me on the bench for every Premier League game so far and I have played in the Carling Cup games, so I can't complain about that.
"I've got to do everything I can in training to show the boss I am ready if he needs me to play against Stoke.
"If I do get the chance to play it will be a massive game for me.
"They have a lot of six-foot-plus lads in their team and it's a chance for me to show that I can be put up against anyone, of stature and size, whoever, and do a good job for the team."
