Tony Mowbray was delighted with an away win, and overdue clean sheet, for Rovers after a 2-0 win at Millwall.

A goal which Joe Nuttall will try to claim, and Adam Armstrong strike, in the space of 60 seconds turned the game on its head.

The first 85 minutes had been attritional stuff at the New Den, with Rovers failing to register a shot on target, or win a corner, in the first half.

But Armstrong made an impact off the bench, replacing Bradley Dack in the 76th minute, a switch that turned the game on its head.

And Mowbray, whose side have now won back to back league games after four successive defeats, “Thank goodness for the last five minutes, I’m glad I didn’t have to pay for the first 85 minutes.

“It wasn’t a very good game of football, but for us it’s a massive three points ahead of two home games in the league.

“It’s an opportunity to keep our season rolling along and see where it goes.

“We put the points in the bag and get ready for the next one against Newcastle.”

Rovers hadn’t won on the road since a 1-0 win at Bolton in October, which was also their last away clean sheet.

In fact they hadn’t claimed one in more than two months before keeping out Millwall, doing so without injured defensive duo Charlie Mulgrew and Derrick Williams.

“Darragh Lenihan was amazing.  Without his normal defensive partner he was very dominant,” Mowbray said.

“Credit to Jack Rodwell, who is very experienced and plays his position well.

“I’m delighted defensively, it was important we got a clean sheet. It feels like a long time since we got one.

“To come away to Millwall and get one was really important.”

Armstrong was part of an attacking Rovers bench, which included Danny Graham, Ben Brereton, Danny Butterworth and Joe Rothwell.

On the reasons for his switch, Mowbray added: “It seemed to be a bit of a stalemate but I’ve been to Millwall before and they score from a set play or a ricochet, and win 1-0.

“It’s great that the substitutes made the difference. It’s always a big decision to take Bradley Dack off and bring on Adam Armstrong.

“You’re taking off arguably your most high quality footballer but bringing on someone with different attributes, speed, and someone who wants to commit defenders as he did for both goals.

“I’m delighted that it paid off.

“He (Dack) got to the point where he was really frustrated. He found it hard to get through their eight man block and they pressed with their two front players.

“They make it difficult for you to do anything but knock it long, which is why the game was so scrappy.

“It wasn’t a day for Bradley because there was no space for him to get on the ball.”
