Rovers have conceded at least twice in nine of their 15 away games and their 31 goals conceded is the most shipped by any Championship side on their travels this season.

At Brentford, Tony Mowbray’s men shipped four unanswered second half goals, having let in three during defeats at Bristol City in September and Swansea in October.

And allowing games to run away from them when falling behind away from home is becoming a real concern for Rovers.

In all three of those matches mentioned Rovers led at half time, only to see points slip through their fingers. They have not lost 22 this term from winning positions.

Mowbray admits it is a concern and believes the problems stem from his side being unable to deal with stretched games.

“It’s an anxiety from the team that they want to get back in it,” he said.

“The main strength of our team is how compact we are from front to back.

“The strikers stay up the pitch because they want to score a goal and don’t come back and help the defenders who are trying to protect the box and the pitch becomes very stretched.

“Good teams like Brentford can pick those spaces.

“Bristol City did it to us earlier in the season, they picked holes late on when they game gets stretched and we have to keep working hard throughout the game, sticking together and making sure we work back as a tight unit.”

Rovers were 2-0 up inside seven minutes at Brentford, but from the moment Ollie Watkins equalised 10 minutes in to the second half, just after Bradley Dack and Danny Graham were forced off injured, things took a turn for the worst.

While the second Brentford goal came from a short free kick, the third was down to an individual mistake from goalkeeper David Raya.

“The scoreline looks ridiculous. It’s a game we felt we should have won from the position we were in,” Mowbray added.

“We gifted some really soft goals that gave them a real impetus and we gave a good team some confidence.

“We were trying to protect in the end rather than do what we did early on which was press high, nick it off them, and when we stopped doing that we were in trouble.”

Watkins’ free shot at goal from the short free kick disappointed Mowbray, but he felt the changes made just before may have played a part in no-one closing down the Brentford attacker.

And the boss felt the substitutes not being up to speed on where to be in those positions, after the hastily arranged changes, may have played a part.

He said: “No team likes losing goals from set plays because you can work on who stands where, who does what.

“I think the substitutions don’t help, it’s difficult to get all that information on to the substitutes because when you’ve been doing the work generally they are on the other team (in training).

“It’s frustrating because if we hadn’t had to make the changes, although they were necessary, we might not have lost those goals.”
