It was a goal in his second Premiership game and Robbie says this will provide him with a big boost as a new signing.
"It will do his confidence the world of good," said the skipper in the absence of Ledley King. "It is important as a striker to get off the mark and full credit to him - hopefully now he can continue it."
Fellow goalscorer in the 2-0 win, Jermaine Jenas, went along with the school of thought, while also aiming praise in the direction of Aaron Lennon for his performance against the Blades.
"He's been banging them in in pre-season games and in training," said the midfielder. "It was nice for him to get one in the league - especially in front our fans at home.
"Aaron has been on fire for a while now and he did exactly what we wanted from him again. He got wide, got at players, managed an assist and was brilliant."
Robbie Keane believes Dimitar Berbatov will be a happy man after getting off the goalscoring mark against Sheffield United last time out.
