There was no late business for Rovers on deadline day, and whilst boss Tony Mowbray is content with his squad, admits that the foreign market may be worth exploiting in the summer.
Aside from Ben Brereton and Brad Lyons' loans being made permanent, Mowbray dipped his toe into the water with the additions of Louie Annesley, who links up with the Development Squad, and Harry Chapman.
The manager kept hold of the core members of his squad, and says he's looking forward to seeing how the group progress from now until the end of the season.
"My own view at this moment is let's see how far we can go with this group," he told iFollow Rovers.
"They're doing ok. They are going to need help as we move forward. We've found this window really expensive.
"For the players that we like and the players that we've asked about, it's really difficult to take from clubs in your own division.
"The player you might have thought cost £1m suddenly costs £10m. It's really tough to buy from this league, which is why I feel we need to expand our scouting system.
"We always have to cover the UK, but we need to cover Europe. We need to start looking at France and Germany and Holland and Belgium and Scandinavia, because there are some diamonds out there.
"Brentford are an example of a team that have gone into the foreign market and found some gems.
"So we need to delve into that market, we need to invest in recruitment in the foreign market and it's something I've talked to the Owners about.
"We're growing as quickly as we can and we have to continue to grow this football club so that we can be really competitive to be able to battle with the top teams in this division."
Mowbray's re-jigged the recruitment side of the club since arriving at Ewood Park almost two years ago, and adds that the time has now come to widen Rovers' net when it comes to transfers.
"We want to get to the point where in every transfer window we have lots of choices and it's just down to the manager to try and pick the player who he thinks is going to improve the team in the area of the pitch that we need improving," he continued.
"I've talked long and hard from day one about how important recruitment is - to buy the right players.
"I feel as though we know just about everything about all the players in our leagues and I feel like we're ready to move on to the next level of recruitment and instead of fishing in a small pond, we need to start fishing in a bigger lake.
"So it's been a bit of a frustrating window, but I'm not annoyed because I like this team. And yet my job is to try and improve this team every window. So we need to start fishing in a European market."
