Investcorp are upset with Elliott Management's negotiating tactics over their attempt to buy AC Milan.
Late interest from RedBird Capital has seen Investcorp's talks with Elliott stall over their €1.2bn offer.
La Gazzetta dello Sport says the Bahrain-based fund are unimpressed by Elliott's tactics.
Elliott reportedly prefer Red Bird's offer due to the formula of the finances, as Investcorp's proposal involved €400m of loans in addition to €800m of equity.
Investcorp are now demanding a quick answer from Elliott with the risk of them walking away from the table.
Indeed, a deadline from Investcorp has now been delivered to American hedge fund Elliott to sell to them.
