Mark Howard was delighted to secure a second clean sheet of the season on Tuesday night and says he wants more.
The goalkeeper was in sparkling form early on against Doncaster, making a vital double save to firstly deny Martin Woods then Chris Brown, but from thereafter he was reduced to a watch briefing as United pushed for that elusive winner.
Speaking on BladesPlayer, the stopper said: "The clean sheet is pleasing but we are disappointed not to have kicked on and won the game.
"It was a tough game and Doncaster came here to set out to make life very difficult for us and they achieved that by keeping a clean sheet themselves.
"It was a frantic start but as the game progressed we got a grip of things and created numerous chances, whereas they didn't really have another sight of goal.
"A lot of goalkeeping is psychological, it is about concentrating and contributing when called upon, like when I punched the ball clear in the final minute. The lads defended brilliantly and that started from the front, the two centre-halves were fantastic, as usual.
"Yeovil will be another tough game, it is always a difficult place to go, but with the ability we have I always fancy us to get a result - and another clean sheet will certainly help."
