Olivier Giroud fired AC Milan back into Champions League contention with the decisive goal in Tuesday's 2-1 win over Paris Saint-Germain.
France striker Giroud thumped home a trademark header four minutes after the break at a pulsating San Siro to reignite Milan's chances of reaching the last 16 and turn around a dreadful recent run of form.
Stefano Pioli's team started the day bottom of Group F but are now well in contention for the knockout stages, third on five points and just one behind PSG who occupy the second qualification spot.
Tuesday's win was revenge for a 3-0 hammering in Paris a fortnight ago and came with Milan's first goals in the competition this season, the hugely impressive Rafael Leao drawing the hosts level in the 12th minute after former Inter Milan defender Milan Skriniar had nodded PSG into an early lead.
Giroud's winner was his seventh goal of the season in all competitions and there was a French flavour to the finish which downed Ligue 1 champions PSG, Theo Hernandez supplying the pinpoint cross from which his Les Bleus teammate netted.
Milan next face group leaders Borussia Dortmund, who took top spot by one point from PSG with their 2-0 win over Newcastle United earlier on Tuesday, in a match which could well be crucial to their chances of getting out of the group.
Their fans also got revenge on public enemy number one Gianluigi Donnarumma who controversially left Milan for PSG as a free agent two years ago and was greeted with a wave of hate from the packed stands.
