Dany N’Guessan’s impact from the bench has given Rob Jones food for thought ahead of Saturday’s derby with Barnsley.
Front two Keshi Anderson and Andy Williams both found the net in Tuesday’s 2-2 draw against Swindon Town.
But the role played by N’Guessan - who came on with Rovers trailing by a goal - has got Jones pondering his selection to face the Tykes.
N’Guessan’s Doncaster career got off to a stuttering start after he suffered a foot injury in pre-season but the 28-year-old French forward has shown signs of making up for lost time in his last two outings.
“Dany came on against Oldham a couple of weeks ago and did really well,” said Jones.
“But then I had to move fast on Keshi because he had quite a lot of suitors who wanted to take him, and now you can see why.
“Dany’s just been unfortunate because he’s come in and done really well. He made a difference again when he came on on Tuesday night.
“I’ve probably given myself a headache for the weekend now with regards to what I do and what personnel I use.”
Jones, meanwhile, was pleased to see Williams notch his first league goal for Rovers.
“He’s a confident boy but when you’ve scored 22 goals the season before there’s a massive expectation on your shoulders,” said Jones.
“It’s up to us as a group to keep him buoyant and keep him moving forward. In front of goal he’s deadly but we’ve got to put the ball in the positions to put him in there and give him the opportunities.
“Against Swindon it was probably the most shots he’s had for a little while so we’re getting there in terms of getting our strikers into the right areas.”
