Tony Mowbray singled out Rovers defender Paul Downing for praise following a standout display during Saturday's 3-0 win over Portsmouth.
Downing has now helped the Blues keep four clean sheets in as many appearances this season, and was excellent at the heart of the defence yet again against Pompey.
Speaking after the game, Mowbray says he's delighted with his defenders and gave Downing a "special mention" for his performance.
“I think the back four are looking really strong at the moment," he said.
“You have to give Paul Downing a special mention, I think that’s four clean sheets in four appearances.
“He looks very assured and composed alongside Charlie [Mulgrew], he helps get the team up the pitch, higher than we’ve been playing.
“He helps the midfield, helps us press and win the ball back, so there were good signs today."
