Rovers hope to make at least one addition before Sunday’s trip to Rangers – including a much sought after goalkeeper.

Tony Mowbray told the Lancashire Telegraph Rovers will look to make two goalkeeping additions before the start of the season after No.1 David Raya was sold to Brentford earlier this month.

Youngster Andrew Fisher has played 90 minutes in both pre-season friendlies so far, though Jayson Leutwiler was back in action last weekend in a behind closed doors game with Rochdale after arriving back from international duty with Canada.

The identity of Rovers’ new stopper is being kept under wraps, with the plan to bring in a more experienced keeper as well as younger option on a permanent deal to compete with each other.

Scott Carson has been on the radar, and looks free to leave Derby County by new boss Philip Cocu, but he isn’t currently the front-runner.

Rovers are yet to bring in a new defender but that chase is also nearing a positive conclusion, with Manchester City defender Tosin Adarabioyo set to arrive on a season-long loan deal.

Mowbray had always been keen to add to his goalkeeping ranks this summer, having been critical of Spaniard Raya last season.

The 23-year-old moved to the Bees in a deal worth an initial £3m which would rise should certain clauses be met, and his departure has intensified the need for reinforcements.

“It is coming to an end I think,” Mowbray said of his goalkeeper search.

“You never know until you’ve got people signed whether they’re going to get done.

“But we’re pretty positive in the next day or two we’ll have some announcements to make.”

Leutwiler, who started the final four games of last season, saw the one-year option in his contract taken up this summer, but it remains to be seen where the new additions would leave the 30-year-old.

Mowbray had previously stated he wouldn’t stand in the Canadian’s way should Rovers bring in the right additions and an opportunity to play more regular football became available.

On the composition of his goalkeeping department, the boss added: “We’re thinking two, but let’s get one done first.

“In an ideal world we’d probably bring in a more experienced one and then a younger one to compete.

“We’ll see which one drops in first.”

Rovers have added three senior players so far this window, Stewart Downing, Bradley Johnson and Sam Gallagher.

They looked well stocked in the midfield and forward areas but are yet to add to their defensive ranks, despite shipping 69 goals last season.

Adarabioyo played 36 times for West Brom last season as they were beaten in the Championship play-off finals.

He will add competition in both central defence, and at right back.
