The manager was happy with the fact his side had ended a run of three defeats and kept a clean sheet, but admitted they can do better.
Kean said: "In the last three games we've been getting double-figure shots on goal but today it wasn't our day and we will have to respect a point.
"I felt we were edgy from the first minute and a little bit frantic. We rushed our passes and never got started. We never got any rhythm into our play.
"A few games ago we were playing fantastically and ending up with nothing. We dug in and to get a clean sheet against a team who scored four against Arsenal last week was pleasing.”
