The Blades sit 23rd in the Championship, six points away from fourth-bottom Crystal Palace, after a 15-game winless streak.
But ahead of the home clash with promotion-chasing Nottingham Forest, Doyle remains buoyant over their chances of survival.
He told the club`s official website: "It has been a frustrating time, having gone so long without a win, but there is nothing better than if the games keep coming rather than having to wait for a Saturday.
"The lads are hurting because we are all professionals and we are desperate to do well and be successful in our careers but nothing seems to be going our way at the moment, despite the plaudits we are earning.
"We still believe we can get ourselves out of the mess we find ourselves in but we can't afford to look too far ahead. We need that first win quickly and then I believe we are capable of going on a good run."
