Stefano Pioli will set his Milan side out to qualify for the Champions League round of 16 in style by beating Salzburg in a decisive San Siro showdown next week.

The Rossoneri moved above Salzburg into second place in Group E on Tuesday with a 4-0 demolition of Dinamo Zagreb at Stadion Maksimir.

Matteo Gabbia opened the scoring with his first Milan goal, heading in a Sandro Tonali free-kick, and the Serie A champions ran away with it in the second half.

Rafael Leao's solo strike doubled their lead, and Olivier Giroud added a third from the penalty spot before a bizarre Robert Ljubicic own goal completing the scoring, with Dinamo's hopes of qualifying emphatically dashed.

Milan now only need a point to advance along with group winners Chelsea, who beat Salzburg 2-1, but head coach Pioli will not be taking a cautious approach to such a crucial game against the champions of Austria at San Siro next Wednesday.

He said: "Two out of three results are not a double-edged sword. We are not mentally and tactically built to manage, we have to play our best to get the win."

The Rossoneri finished bottom of their group last season, and Pioli believes reaching the last 16 would show the strides they have made.

He added: "I think it is clear that our growth comes from qualification. We have to play with our mentality, and it is the next step, where we would show that we are doing better than last year.

"We must close the discussion next Wednesday without forgetting the championship. We need concentration for the league match against Torino [on Sunday]. Then we will have the time and attention necessary to take care of the next Champions League match in the best possible way."

Pioli praised centre-back Gabbia, who was rock solid at the heart of the Milan defence after coming in to replace the suspended Fikayo Tomori.

"I continue to be convinced of the strength of my group," he said. "I emphasise Matteo's seriousness, but also his skills. He has a sense of position, physicality and skill in aerial duels."
