Portugal Colonial - Calhanoglu fires Inter to Champions League win over angered Arsenal

Turkey captain Calhanoglu rifled home the winning penalty in first-half stoppage time to put Inter on 10 points at the halfway point of the new single league phase.

Unbeaten Inter are one of four teams to sit two points behind leaders Liverpool and look a good bet to finish in the top eight places which offer direct qualification for the last 16 as they are yet to concede a goal.

"The boys were magnificent. We beat a really good team, who have been fighting with Manchester City," Inter coach Simone Inzaghi told reporters.

"Tonight was a night to remember because we played in front of a stadium which pushed us on all the way, and we deserved to bask in their applause."

Arsenal meanwhile continued their shaky run of form and sit 12th on seven points, although Mikel Arteta's team deserved more from an engaging encounter at the San Siro.

Arteta was angry at the decision to give Inter's penalty, for Mikel Merino handling Mehdi Taremi's flick, as he believed his defender couldn't get his arm out of the way.

He also couldn't believe that his team weren't given a spot-kick early in the first half when Sommer clattered into Merino -- who was substituted at half-time due to the impact -- while trying to clear the ball.

"If you are going to give a penalty, the other one has to be because he punches him in the head," he said to TNT.

"There is no deflection, nothing you can do in the box, so can he get away from it? If he is going to give that the other has to be 100 percent a penalty."

Calhanoglu's winner was the first goal Arsenal have conceded in the Champions League this campaign and came on his first start since picking up a thigh injury on international duty last month.

- Inter march on -

His third goal of the season was followed by a clutch of good chances for the away side who were denied a leveller in the second half by a combination of desperate defending and one spectacular Yann Sommer save from Kai Havertz.

Inter now face Serie A leaders Napoli on Sunday with the chance to move top after five of Inzaghi's first-choice players -- including Italy stars Nicolo Barella and Federico Dimarco and France forward Marcus Thuram -- started Wednesday's match on the bench.

Arsenal face Chelsea at Stamford Bridge as they try to snap a run of three Premier League matches without a win and get a faltering season back on track.

Arteta will be able to count on his skipper Martin Odegaard after the Norway international made an appearance as a late substitute for Havertz.

Odegaard had missed Arsenal's 12 previous matches after picking up an ankle injury with his country, and his return is a boost for Arteta who is also sweating on Declan Rice who played no part at the San Siro.

Inter started on the front foot and were unlucky not to be ahead in the first minute when Denzel Dumfries crashed a powerful strike off the crossbar.

But little else happened until just before break when Merino's contentious handball led to Calhanoglu's neatly slotted spot-kick.

With that lead and Napoli coming up on Sunday, Inter tried to soak up Arsenal's pressure, but after Dumfries had to scramble to clear off the line and Sommer somehow tipped away Havertz's dipping effort, Inzaghi called upon his stars from the bench.

Thuram, Barella and Henrikh Mkhitaryan all came on in the 62nd minute but Arsenal kept pouring forward.

And Havertz had his head in his hands in disbelief in the 75th minute when he spun and let off a shot which seemed destined for the net until Yann Bisseck flung out a leg to save the day for grateful Inter fans.
