MILAN — New coach, more disappointment for AC Milan.

Rodrigo Becao scored his first professional goal to help Udinese beat Milan 1-0 as new Rossoneri coach Marco Giampaolo's first match in charge ended in defeat on Sunday.

Giampaolo replaced Gennaro Gattuso in June and the former Sampdoria coach is already ready to give up his favoured 4-3-1-2 formation after a disappointing performance in which Milan didn't even have a shot on target.

"Certainly you'll see them in a different formation. I have to make them play in their natural roles," Giampaolo said. "I saw things that weren't done well because of the characteristics of my players.

"Today's match gave me a lot to analyze and the three up front have to develop into a different attack."

Becao, who was signed by Udinese in the off-season, headed a corner into the bottom right of the net in the 72nd minute.

The 23-year-old defender was signed from Brazilian side Bahia but had spent last season on loan at CSKA Moscow.

Milan thought it had a penalty after Alessio Romagnoli's header appeared to hit Samir on the arm but, after viewing it several times on the pitchside monitor, the referee deemed it involuntary.

MORE NEW COACHES

Roma and Genoa also have new coaches in Paulo Fonseca and Aurelio Andreazzoli, respectively, and the two teams played out an entertaining 3-3 draw.

Roma will be the more disappointed of the two after leading three times thanks to goals from Cengiz Under and Edin Dzeko, and an Aleksandar Kolarov free kick that hit the underside of the bar and dropped down just over the line.

However, Genoa fought back each time through Andrea Pinamonti, Domenico Criscito (penalty) and Christian Kouamé.

Luis Muriel scored twice as Atalanta fought back from two goals down to win 3-2 at Spal.

Atalanta surpassed all expectations to finish third in Serie A last season to qualify for the Champions League for the first time in its history.

Serie B champion Brescia won 1-0 at Cagliari, with Alfredo Donnarumma — last season's top scorer in the second division — scoring the only goal from the penalty spot.

Another newly promoted side, Hellas Verona, drew 1-1 at home to Bologna despite playing most of the match with 10 men after Pawel Dawidowicz was sent off in the 13th for a dangerous tackle on Riccardo Orsolini.

Elsewhere, Lazio won 3-0 at Sampdoria and Torino beat Sassuolo 2-1. Lazio and Italy forward Ciro Immobile scored twice to take his tally to 101 Serie A goals.
