Ba netted twice on his debut as the Blues ran out 5-1 winners in an FA Cup clash with Southampton on Saturday, underlining his status as a potential threat to the £50 million Spaniard's place.
And, ahead of his side's Capital One Cup meeting with Swansea, interim coach Benitez has refused to be drawn on who will lead the line.

He told reporters: “It is good for me because before I didn’t have to think about which striker to choose. I prefer to be in a position where I can choose one or the other.
“It’s important to have options, especially if you have two games in four days. We have different options.
“I have an idea who will start. It depends on how they feel and perform. There’s no rule about one playing in this game and the other in the next. I’ve spoken to Fernando a lot and with Demba and they know what I am expecting of them.
“We have now two good players, two good options, and both will compete. I can see everything positive in terms of the team now.
“Talking with Demba and Fernando, they both know they have to compete and play well. It can bring the best out of both of them.”
