DONCASTER have been warned to rediscover their killer instinct at Valley Parade.

Boss Grant McCann was furious with his side’s 1-0 home defeat to lowly Bromley in midweek.

Rovers will probably be glad to be back on their travels for the Yorkshire derby.

They have netted five in successive wins at Grimsby and Swindon but have found things harder on their own turf – scoring just twice in the last four home games.

McCann has hinted that there could be changes in the January transfer window if his team do not buck up.

He said: "Good groups are great to have. But I want a group full of killers.

“People who want to put their body on the line to score a goal, to get hurt, to get us in games.

"I'm not sensing that in the group at the moment so it's my job to get it out of them and find a way to be much more clinical. Because January comes around quick.

“I've said that to the players, because if they're not going to do it then I haven't got time to wait this season. We haven't got time to wait as a football club.

"We know where we want to be, so it's important we get that right."

Doncaster surged into the play-offs last season on the back of a 10-game winning in March and April. They lost just once in the league after City beat them in the Bristol Street Motors Trophy quarter-finals.

Expectations are high to take that form once step further this time with promotion – and McCann is laying it on the line.

"I'm aiming that at us as a team, not just the forwards or midfielders," the Northern Irishman told the Doncaster Free Press. "We all need to be better, simple as that.

“I said three weeks ago that we've not got enough ruthless edge or enough killers in there at the minute and that's really annoying for me.

“There's no point having all the ball, creating all these chances and then not scoring. You can float around the top six, top seven with the way we're going at the minute.”
