Craig Levein has said that he still has plenty of work to do to improve Hearts after they drew 1-1 at Partick Thistle.

Ross Callachan's equaliser earned his side a point and kept Hearts' unbeaten run since Levein returned to the manager's role.

The former Scotland boss said that he already saw plenty of progress since he took charge but there was room for improvement and he still had to impose a playing style.

"We're not at the stage yet where I can feel completely comfortable about the way we're playing," he said.

"I am much, much happier with the way we're working and the effort the players are putting in and the fitness figures.

"The first thing was to fix the effort and application, and we're getting that but now we have to fix our style of play.

"We can do better than what we've done."

Levein had no complaints about the result at Firhill, saying: "I thought it was a tough match, I don't think any team had domination for any length of time, it seemed to swing back and forth throughout the 90 minutes.

"I was pleased that we showed good resilience and I was hoping that resilience would extend to a goal at the end and get all three points, but all credit to Partick."
