Manchester City's commitment so far has come in the form of a clear verbal indication to Leipzig rather than a formal offer, following several rounds of talks over the highly rated Ivory Coast international.
That has proven insufficient so far to draw City level with rivals Liverpool and Real Madrid, both of whom have already submitted official €100m bids that Leipzig have rejected, with the Bundesliga club holding out for a fee in excess of that figure. Paris Saint-Germain, said to be Diomande's preferred destination, have yet to lodge any offer at all.
City's interest in Diomande is far from new, with the club having been credited among his suitors for well over a year. Reports earlier this week detailed how both City and Arsenal had signalled a willingness to pay a nine-figure sum for the winger, and Hinze's update corroborates that City's willingness has so far existed only at the level of verbal assurances rather than concrete financial commitments placed on the table at the Etihad.
Whether City ultimately convert that stated interest into a formal bid remains to be seen, with the club continuing to monitor the situation as Real Madrid press ahead with their own pursuit. Real's advances could yet force City's hand, either prompting a serious offer or persuading City to shift their focus elsewhere given the scale of competition already involved.
Diomande, who joined RB Leipzig from Leganes for around €20m last year, scored 12 goals and provided nine assists in 33 Bundesliga appearances last season and impressed further for Ivory Coast at this summer's World Cup, continuing to attract suitors from across Europe's elite as the transfer window enters its closing weeks, with his combination of pace, dribbling and versatility across the front line making him one of the most sought-after young attackers on the continent this summer.
