Barcelona qualified for the Champions League knockout stages despite Mauro Icardi's late strike handing Inter Milan a 1-1 draw at the San Siro on Tuesday
Needing a victory to confirm their passage to the last 16 as group winners, Malcom gave Ernesto Valverde's side, who were still without the injured Lionel Messi, the lead minutes after coming on as a substitute (83)
But Inter captain Icardi capitalised on some poor defending from Barca to equalise just four minutes later (87), leaving the visitors waiting to secure top spot in Group B
Barcelona, who were unbeaten in their last 11 group stage games in the Champions League going into the match, started in confident fashion as Inter needed Samir Handanovic to keep out Ousmane Dembele's powerful effort in the second minute
The visitors dominated possession with Inter always looking to counter and they almost broke the deadlock when Ivan Perisic's low cross picked out Kwadwo Asamoah, but the defender failed to hit the target from close range
Barca were looking the more likely side to break the deadlock though and they should have been in front in the 31st minute
 Inter failed to clear Dembele's corner and Gerard Pique kept the ball alive, knocking it down to Luis Suarez, who sliced wide from a tight angle
Philippe Coutinho then forced an excellent save from Handanovic, who also kept out a first-time effort from Suarez to keep the scores level at the break
Barcelona continued to dominate after the break and Handanovic made his best save just before the hour mark, blocking Ivan Rakitic's goalbound shot, but he was blameless for Malcom's opener
The Brazilian has not featured much for Barca since signing from Bordeaux in the summer but he made an instant impact after replacing Dembele, controlling a pass from Coutinho before powering the ball under the diving Handanovic for his first goal for the club
Barca were on their way to a first win in Italy since November 2011, which would also have seen them seal top spot in the group, but Icardi had the final say with his ninth goal of the season
Despite the late leveller, Barca could still celebrate qualifying for the knockout stage for a 15th consecutive season and they will clinch top spot in the group if they win away at PSV Eindhoven next time out
Inter are unbeaten in their four home games against Barcelona in the Champions League, drawing three of those fixtures (W1)
Barcelona have only lost one of their previous 15 games in the Champions League (W9 D5), however, four of the six games they failed to win in this run came against Italian opposition
Malcom is the first player to score on his Champions League debut for Barcelona since Cristian Tello, who netted twice v Bayer Leverkusen in March 2012
Inter Milan played out just their second draw in their last 21 Champions League games (W10 L9), with their previous one coming against Trabzonspor in November 2011
Each of Inter's three goals at the San Siro in the Champions League this season have been scored in the 85th minute or later, with Icardi netting two of those
Icardi will get plenty of plaudits for his late equaliser but Handanovic is the man Inter really have to thank for their point
He was called on time after time to repel Barca, producing stunning saves to keep out Suarez, Coutinho and Dembele
He was finally beaten by Malcom in the 83rd minute but Icardi popped up to ensure the Slovenia international deservedly did not end up on the losing side
