Paul Warne hailed his Rotherham side as “unstoppable” in the first 45 minutes of their 5-0 romp over Southend, but refused to get too giddy.
In a display that matched their pre-season promise, the Millers blew Phil Brown’s side away in the first half, with a stunning Kieffer Moore hat-trick and a brilliant Joe Newell strike.
Ryan Williams’ effort after the break put the finishing touches on their biggest win since March 2014 and only their third in the league of 2017.
Warne said: “I have been banging the drum at how we want to play this year, I want to play aggressive, physical football and I thought in the first half we were excellent and virtually unstoppable.
“The pessimist in me said we need another goal at 3-0. I thought 3-1 at half-time would have been a disgusting scoreline so to get the fourth before half-time was great.
“We had to keep them on the floor at half-time, a few of them were smiling. In the end it sort of dribbled out.”
