Darren Ferguson felt Rovers were made to pay for a slow start as they fell to defeat at Northampton Town.
Matt Crooks’ early goal was enough to seal victory for the Cobblers, which left Ferguson having to change the gameplan.
He said: “We made the worst possible start, which meant we couldn’t do what we wanted to do - which was to hold the ball and frustrate them.
“At 1-0 we had a lot of the ball, but didn’t move it quick enough. In the second half we played well, and in the last 15 minutes had some real urgency because we were 1-0 down. If we played like that for the full match it’d be different.”
It was Jimmy Floyd Hasselbaink’s first game in charge of the home side, and Ferguson reckons he will do well.
He added: “We needed to concentrate on our own game. It’s the same players who have been beaten four games on the bounce.
“Jimmy is a good manager. We made it easy for them in the first-half as some of the passing was too slow.”
