Paul Dickov is staying firmly tight-lipped about whether he plans to add further new faces.
The Scot is understood to be keen to bolster his defensive options and recruit at least one more forward-thinking midfield player.
But he was keeping schtum after Tuesday night’s friendly draw with Nottingham Forest.
Asked if there would be any more additions this week, Dickov said: “I’m not going to say.
“If I say ‘this week’ everyone jumps on the bandwagon if it’s next week so I’m going to shut my mouth. I’m not saying a word.”
He later added: “Look, we’re speaking to people.
“But I’ve always said we have to make sure it’s the right ones.
“We’ve had to be patient to get the ones in we have done.
“If I think it’s the right one I’ll wait for the right time to do it.”
Left back Aaron Taylor-Sinclair made his first Rovers appearance in the encouraging 1-1 draw with the Reds following his free transfer from Wigan Athletic.
Fellow new arrivals Thorsten Stuckmann, Gary MacKenzie and Andy Williams also featured but Richard Chaplow was ruled out with a knee injury.
“What I’ve done so far I’m delighted with,” said Dickov, on his transfer business.
“When you recruit it’s important to improve and I think with all five players we’ve signed we’ve done that.”
Reflecting on pre-season to date, he added: “Fitness-wise the boys are flying.
“We need to get minutes on the pitch into them now and work a lot more on how we want to play tactically, with and without the ball.
“The most pleasing thing so far has been the attitude and the togetherness of the boys.
“A few of the senior lads have been to see me to say Portugal was one of the best training camps they’ve had.
“What we’ve got to do now is take that on.”
Rovers host Middlesbrough on Saturday (3pm) and Sunderland next Wednesday (7.45pm).
