But McCarthy has no doubt they will provide the goals Wolves need to stay in the top flight.
Ebanks-Blake is fully fit after straining his hamstring on the opening day of the season against West Ham.
"We know what Sylvan's attributes are. When he gets chances, Sylvan puts the ball in the net," McCarthy spelled out.
"He has been clinical since he came here. Unfortunately for him, and for us, he has not had the chance to be starting every week this season.
"It has been stop-start for Sylvan so far this season - but since we signed him, he has been our talisman and is the one who has scored the goals."
Ebanks-Blake opened his account for the season - and grabbed the first Premier League goal of his career, from the penalty spot - against Aston Villa last weekend.
McCarthy is convinced he can build on that and added: "The goal he got against Aston Villa last weekend will have been a big boost to his confidence.
"If you listen to what he has said over the week, I am stating the obvious. It will have given him a big boost, because that is what he is about."
McCarthy splashed out £6.5million to sign Doyle from Reading during the summer - and already believes it is money well spent.
Republic of Ireland international Doyle has scored three goals so far this season, and McCarthy added: "I knew what I was getting when I signed him.
"He has been everything I thought he would be - and he is a great lad.
"'Doyler' is a good footballer - and the fans have taken to him as well, because he plays well and scores goals.
"He is such a likeable character, and anyone who has spoken to him will know that."
Despite the high regard he is held in by McCarthy, Doyle will never take his place in the side for granted.
He said: "With the players we have here, you don't have to be off form for too long before you are out of the team.
"There is plenty of competition for my place in the team, but that is why I am enjoying it.
"You work that bit harder in training and in the gym to make sure you stay in the team.
"I have been very happy with my overall performance, and the goals have topped that off.
"There would be no point in me sitting here saying I have played well if I haven't scored - because I have been brought here to get goals.
"I am glad that the goals have come with the performances, to put the icing on the cake."
