Kovac is now eyeing a place in Avram Grant's XI for the midweek Carling Cup third round tie at Sunderland.
He told whufc.com: "It was good for us to get a point because it was a very hard game. We have lost our last three games, so to get a draw and not lose gives us a real boost. From now, our confidence can get better and better and better.
"I enjoy the physical battle against Stoke every time, putting in challenges and winning headers.
"We go to Sunderland on Tuesday and we need to get a result there to set us up well for Tottenham. We have two important home games coming up and I hope to be in the starting lineup for both of them."
