Rovers boss Steve Kean has suffered a frustrating time in the transfer market so far this summer missing out on several targets.
Lansbury has now emerged as a target with Kean desperate to reinforce his squad before the transfer window slams shut.
The England-Under 21 midfielder, who made his Gunners debut in 2007, helped Norwich City to promotion last season and was almost named the Championships Young Player of the Year.
It was thought that Lansbury would finally stake a claim for a starting berth at the Emirates Stadium next season especially with Cesc Fabregas’ leaving for Barcelona and Samir Nasri on the verge of a move to Manchester City.
However it seems that manager Arsene Wenger may be willing to cash in on the 20-year-old, which has alerted Blackburn.
A move to Ewood Park would certainly guarantee Lansbury first team football every week although whether he would be prepared to leave North London remains to be seen.
If Kean were to persuade the midfielder to join Rovers it would be a sizeable coup for the club and a major breakthrough in the transfer plans.
