Aarons has joined the southern club for an undisclosed fee, initially estimated at £9 million ($11 million), with potential additional payments that could raise the total to £12 million ($15 million).
These additional payments are considered attainable targets, and Norwich is confident they will receive a substantial portion of the £3 million ($4 million).
Norwich, which had been constrained by a limited budget during the summer transfer window, had aimed to capitalise on Aarons’ situation with only one year left on his contract.
Prior to Bournemouth’s intervention, Aarons had already undergone a medical assessment with Daniel Farke’s Leeds team, and Southampton’s bid had also been accepted.
Bournemouth is set to commence their Premier League season with a home match against West Ham on Saturday.
However, Aarons is unlikely to participate in this fixture since he hasn’t yet trained with Andoni Iraola’s squad.
