Inter s recent revival under Luciano Spalletti makes Wednesday s Milan derby impossible to call, according to Hernan Crespo.
After a stunning start to the season that saw the Nerazzurri top Serie A in December, their league campaign stuttered with a run of nine games without a win.
That ended any hope of the Scudetto for Spalletti s side, but three wins in their last four have reignited their Champions League dreams.
And Crespo, who had spells with both Milan clubs between 2002 and 2009, believes Inter s resurgence means their midweek clash could go either way.
Probably until a month ago everyone would have said [AC] Milan are favourites, Crespo told Omnisport, speaking courtesy of Hublot.
That s not because their players have changed but they have modified something in the way they approach and prepare for a game.
But have you watched what Inter did [against Sampdoria and Verona]? They woke up.
Crespo added: In a derby, who s the favourite doesn t really count much. Since [Gennaro] Gattuso arrived, I have to say things look a lot different for AC Milan.
[But] Inter are alive again and I m sure we will see a nice match.
