Ba's January arrival from Newcastle United has provided some healthy competition for Torres as the manager makes it clear he will not be playing favourites with his fellow countryman.
"I've spoken to Fernando a lot and with Demba and they know what I am expecting of them," he said ahead of Wednesday night's Capital One Cup semi-final first leg against Swansea City.
"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."
