Gabriel Jesus struck a first-half brace to fire an unstoppable Arsenal to an impressive 3-1 victory against Inter Milan and confirm their place in the last 16 of the Champions League.

Jesus opened the scoring at San Siro after just 10 minutes before Petar Sucic blasted the hosts level eight minutes later.

However, Jesus doubled his tally in the 31st minute and substitute Viktor Gyökeres struck six minutes from time as Arsenal recorded their seventh triumph in as many matches in Europe so far.

Arsenal, who have already seen off Bayern Munich, Atlético Madrid and now last year's beaten finalists and remain the only team in the competition to have won all of their group fixtures, are guaranteed to finish in the top two.

It means Mikel Arteta's side will be assured of hosting the second legs in their knockout matches.

"We're very proud, not only for tonight's game, but for what we've done in the competition so far, and with one game to go to be already in the position that we want to be in," Arteta said after the match. "It is a massive prize to the team because we know how difficult it is.

"We really had the hunger and desire to come to a place like this against a top, top side and prove what we are and what we can do. We have ambition and the conviction that we can compete against any team. I love the attitude to come to this atmosphere against the opponent that we had.

"The team has matured, are very ambitious and emotionally very controlled. We have to carry on going."

Arsenal have one final group game -- a home contest against Kazakhstan's Kairat a week on Wednesday -- where a point will be enough to confirm them as winners of the 36-team group.

Jesus, among seven changes by Arteta ahead of his side's pivotal Premier League clash against Manchester United, was making his first start in Europe in 405 days in place of Gyökeres.

And the Brazilian's eye-catching performance could see Gyökeres, despite his late goal, warm the bench again for the visit of Michael Carrick's side on Sunday.

Jesus struck his first after 10 minutes after popping Eberechi Eze's pass to Mikel Merino, who in turn found Myles Lewis-Skelly.

His pass across the box was scuffed goalwards by Jurriën Timber and Jesus was on hand to convert the full-back's strike with an outstretched right foot.

The home side took just eight minutes to respond. Cristhian Mosquera, playing for the first time since Dec. 3 following an ankle injury, pulled off a fine sliding tackle to thwart Marcus Thuram before Lewis-Skelly did enough to divert Nicolo Barella's shot clear -- but Sucic's crisp side-footed strike from the edge of the area proved impossible for a diving David Raya to keep out.

A chance for Eze followed but he dragged his effort wide. Then Mosquera did well to prevent Sucic from getting a shot away when he was left outnumbered on a three-against-one breakaway, and Thuram could only blaze over.

Just four minutes later, Jesus had his second. Saka's inswinger found Leandro Trossard at the back post and his header back towards goal was headed in by Jesus from underneath the Inter bar -- Arsenal's 19th goal from a corner so far this season.

Saka and Luis Henrique fired wide at either end before a strong left hand from Raya denied Federico Dimarco.

After the break, the influential Eze might have made it three only to fire his shot straight at Yann Sommer. Trossard's volley from Saka's cross then drifted just wide.

Jesus might have turned provider on the hour mark but Alessandro Bastoni's lunging tackle prevented Saka from scoring. Saka then stung Sommer's hands with 13 minutes left.

There were moments for Inter at the other end, too, but Raya's goal rarely came under significant threat.

And Gyökeres put the finishing touches on yet another statement victory for Arsenal when he swept home from the edge of the box in the closing stages to allow the boisterous travelling support, who greeted every Arsenal pass with "oles" prior to the final whistle, to dream of a first Champions League title.

For Inter, the defeat leaves them staring at the probability of a play-off tie to reach the next stage.

Head coach Cristian Chivu said: "I am never worried. We knew the Champions League journey would be difficult.

"We don't know if it will be enough, but we are ready to play the play-offs if necessary. Arsenal deserved to win tonight because they seized the opportunity, and they were stronger than us."
