The Rossoneri are fighting for a place in the last 16 of the competition and Pioli has decided against ‘fixed reference points’ in the attacking trident.
Thus, he seems set to pick three lively players who are capable of rotating in the trident and moving between the lines.
Krunic, Diaz and Messias are expected to support Ibrahimovic in attack against Jürgen Klopp’s men.
Mike Maignan is set to start in goal, with Pierre Kalulu at right-back, with Fikayo Tomori and Alessio Romagnoli in the heart of the defence. Theo Hernandez is certain to start at left, while Sandro Tonali and Franck Kessie should be in the middle of the park.
Probable line-ups: Milan vs. Liverpool
Milan (4-2-3-1): Maignan; Kalulu, Tomori, Romagnoli, Theo; Tonali, Kessie; Messias, Diaz, Krunic; Ibrahimovic
