DEAN Saunders hinted at more new arrivals after seeing his side well beaten by Leeds, stating his squad lacks “Roy Keane” type characters.
Rovers started the game brightly but after falling behind to Danny Pugh’s tap-in never looked like scoring against their West Yorkshire rivals.
Goals from Ross McCormack and Tom Lees then rubbed salt into Doncaster’s wounds as the home side were second best in almost every department to United.
Saunders admitted after the game he isn’t sure whether he has enough players with a Keane-like mentality, who can roll their sleeves up and scrap for points.
He said: "I've learnt more from this game than the three games previous.
"Sometimes the results can paper over the cracks.
"I've got to think about the personnel we've got and the way we're trying to play.
"Have we got the right kind of players for what I want them to do?
"We've got lots and lots of nice pretty footballers, but we haven't got many Roy Keane-types who can play three different ways.
"He's fitter than you, he's more aggressive than you and he can play football better than you.
"If our football's not working we struggle to resist.
"And if our football’s not working we've got to be able to roll our sleeves up and grind out points.
"I don't know whether I've got the personnel to do that.
"We gave three terrible goals away,” he added.
"I thought we started the game well but then we gave a daft foul away by the corner flag and the lad taps it in from five yards out - it was a disastrous goal to concede.
"The third goal was a free header from a corner.
"That was a disaster as well.
"We've got another game on Tuesday now and we've got three days to regroup and try and get a result at Blackpool."
