Following their midweek match in the Champions League, Chelsea were faced with having to field their tertiary choice striker against Manchester United - Didier Drogba.
That is because Diego Costa is reportedly hamstring while Loic Remy faces a number of weeks on the sidelines.
However, Jose Mourinho has allayed fears the club will be without Costa by suggesting the lethal Spaniard could even be fit to face United this weekend.
"Diego has a chance, he has a little chance," confirmed the Blues boss.
"Remy, no chance. Diego a little chance, the same as [John Obi] Mikel and Ramires. The only one I can confirm has no chance is Remy."
He added: "We will see what happens by Sunday. Remy has no chance, Diego has a little chance."
Manchester United will be buoyed by their own fitness boosts as Angel di Maria and Ander Herrera are both available for selection.
"Ander Herrera was already fit for the last game and [as for] Di Maria, I said after the [West Brom] match that it should be not so heavy," said Louis van Gaal. "He has trained on Thursday so no problem."
As quoted by Sky Sports, van Gaal also spoke about the apparent influence he had on a younger Mourinho, when the Special One was first starting out in the football industry.
"He talks about Louis van Gaal and also Bobby Robson, and I appreciate that, but you always do it by yourself," Van Gaal said.
"I was also an apprentice when I was the assistant coach of Leo Beenhakker (at Ajax) and it's good that my eyes were also open at that time.
"And it's good that Jose Mourinho's eyes were very open when he was my assistant, but you do it by yourself."
Mourinho will not let any niceties get in the way of his mission on Sunday as the Portuguese coach has vowed to collect maximum points.
"We go to every match to win but sometimes games go in one direction where in a pragmatic way you feel one point becomes a good result," he said.
"[On] Sunday we go to win," Mourinho concluded.
