Jones, a £6million signing from Southampton, tore Reading to shreds and might have completed a hat-trick to announce his arrival on Wearside in style, and his manager could hardly have been more delighted.
Keane said: "It wasn't bad, was it? Very, very good. I thought he did quite well a few weeks ago.
"It's tough for him being up front on his own, but he gives us something a little bit different to the other good strikers we have got at the club.
"He worked very well with Michael Chopra and it was a very good home debut."
