Milan face Fiorentina in the biggest game left this season to decide who will snatch the last Champions League place.
The Viola need to win this game to cut the gap between the two sides to three points, while a draw or a Rossoneri win will all but decide who will represent Italy in next season's Champions League, even if the order is yet to be known.
Vincenzo Montella has got a new tune out of his side in recent weeks, experimenting with a back four over the tried and tested 3-5-2.
It could come into play again against Milan's potent attacking trident. Otherwise, the Rossoneri might have a mismatch in the wide areas with Stephan El Shaarawy and M'Baye Niang.
There will be explosive battles all across the field, and here are three to keep an eye on in particular.
