A win for Lazio today will surely be the final nail in Massimiliano Allegri's coffin. Can his Milan side bounce back from that costly 1-0 defeat in the Milanese derby and kickstart their season? My name is Max Bentley and I'll be keeping you up-to-date with all the action from the Stadio Olimpico.
Without further ado, let's bring you tonight's lineups...
Milan (4-3-1-2): Amelia; Abate, Bonera, Yepes, Antonini; De Jong, Nocerino, Montolivo; Boateng; El Shaarawy, Pazzini.
A bit of pre-match entertainment at the Stadio Olimpico as an eagle flies around the ground with blue and white ribbons between its talons. Great atmosphere and plenty of flag-waving too!
In the last league meeting here between the two sides in February, Lazio triumphed 2-0 with goals from Hernanes and Tomasso Rocchi.
This game will surely tell us whether Lazio are capable of sustaining a Scudetto challenge. Let me know your thoughts and predictions on Twitter @MaxBentley1.
Stefano Mauri and Daniele Bonera exchange captain's welcomes and it will be Lazio who get this Serie A clash underway. A smile on the face of Allegri prior to kickoff. Will he still be smiling come full time?
HALF TIME AT STADIO OLIMPICO: LAZIO 2 - 0 MILAN. Lazio sprung to life after a dull 25 minutes through the brilliance of Hernanes before Antonio Candreva scored what will surely be one of the goals of the season. Lazio looking a good bet for all three points here. Will Massimiliano Allegri be able to salvage his Milan career in the second half? Let me know your thoughts on Twitter @MaxBentley1.
Milan's worse start in over 80 years looks set to continue at this rate as they are heading for their fifth defeat in eight Serie A games. Will Allegri ring the changes at half-time?
Here's the first-half analysis from my Goal.com correspondent Renger Dotinga: "Milan devoid of ideas, and deservedly two goals behind. Not even a shadow of the team that nearly retained the title last term."
Ahmed Sheck on Twitter: "Allegri switched back to 4-3-1-2 which failed to produce in the beginning of the season, we need miracles, is pato the savior?"
A few of you saying that you would like to see Allegri sacked even if Milan can stage a remarkable comeback. Who would you want to take the Rossoneri reigns?
It seems that Urby Emmanuelson will replace Kevin Prince Boateng for the second half. Could Alexandre Pato feature for the first time since that Champions League loss against Barcelona back in April?
FULL TIME: LAZIO 3 - 2 MILAN. Massimiliano Allegri's side crash to a fifth league defeat of the season despite a brave second half fightback. Lazio move to within one point of Napoli in third place as their impressive start continues.
Could that be the end of the road for Massimiliano Allegri? Their Scudetto challenge up in flames, can Milan redeem themselves in the Champions League away at Malaga in midweek?
Milan have now failed to beat Lazio in six consecutive league meetings. Their last victory came in a 2-1 win back in November 2009.
So, the Milan rot continues as Lazio claim a valuable three points in their Scudetto bid. If you haven't already seen it, make sure to check out the golazo by Antonio Candreva. That's all from me, Max Bentley, on what has been a pulsating affair at the Stadio Olimpico. Good night.
