Sam Allardyce has a fully fit Sunderland squad to choose from for the visit of Chelsea.
But he hasn't ruled out making changes to either his system or personnel for the crunch Premier League game at the Stadium of Light.
Seb Larsson, Jack Rodwell and John O'Shea again had to make do with a place on the bench for the draw at Stoke City.
When asked if he was considering making changes to his side, with several experienced campaigners among the subs, Allardyce added: "There is that consideration.
"Also, the team didn't play too well on Saturday, so does that make me say [to some of the others] here is your opportunity?
"Go and do better than the lads you are replacing.
"Me and the staff will take all aspects of this week and all aspects of the last performance into consideration and tactically how we think Chelsea will play and pick a team accordingly.
"There maybe the possibility of a couple of changes. If not system, then personnel or maybe both."
Allardyce was left frustrated by his side's performance at the Britannia Stadium despite Jermain Defoe's last-gasp equaliser from the penalty spot.
"We are all looking okay. The team has been consistently allowed to perform," Allardyce told the club website when asked if he had a fully fit squad to pick from.
"We missed a trick in possession [against Stoke City] though as we didn't perform as well as we should have done.
"If we had done, then even with the referee's bad decisions, we would have won the game.
"I am going to work on that side of the game this week to break down a very good team in Chelsea."
Allardyce also moved to congratulate Leicester City, who were crowned Premier League champions after Tottenham Hotspur were held to a 2-2 draw by Chelsea in a fiery contest at Stamford Bridge.
He added: "Having watched Leicester and Manchester at the weekend, the reason why Leicester are where they are is because they are the best team.
"Tottenham might have better players, City and Chelsea might have too but Leicester are the best team.
"They function better and have only lost three games all season. It shows why they have won the league.
"Chelsea v Tottenham is a fierce derby - as is Newcastle and Sunderland - and the last thing a Chelsea fan wants is for Spurs to win the league.
"The players know that. It will always bring a bit more spice to the occasion.
"It looked like Tottenham were handling the occasion much better than Chelsea but it is amazing what a goal does to change a game.
"We are looking for something similar in the next three games."
