Rovers turned down an initial offer, according to the Scotland international, from their Sky Bet Championship rivals for the prolific forward who cost them £8m from Huddersfield Town in 2012.
But Rhodes has now broken his silence on the possibility of a move, with Boro reportedly willing to spend £12m to secure his signature, and he admits to having been impressed by Aitor Karanka’s side last season when they made it to the play-offs,
“I have been advised by the club that they have rejected an offer from Middlesbrough for my services which was in excess of what Blackburn paid for me,” he told ESPN FC.
“I am ambitious and have never hidden my desire to play at the highest level possible and that was one of the reasons why I left Huddersfield Town for Blackburn.
“When I left Huddersfield I felt the timing was right in the next stage of my career and, having seen Middlesbrough’s performances last season in reaching the play-off final and their ambition this summer in terms of acquisitions, I would have liked to have been able to talk to them and I am unhappy at not being given that opportunity.”
