Inter Milan defeated Arsenal 1-0 in the Champions League on Wednesday night, while a 93rd-minute goal ensured Atletico Madrid left Paris with a win over Paris Saint-Germain (PSG).

A penalty taken by Hakan Calhanoglu three minutes into first-half injury time gave Inter the victory over Arsenal.

The match at the San Siro looked set to go into the break goalless until a penalty was signalled against Mikel Merino after Mehdi Taremi’s flick deviated the ball into the Arsenal player’s raised hand from close range.

The Italian champions remain undefeated in the competition this season and sit fifth on 10 points at the midway point of the new league phase format.

“I think we played a great game against a strong side who play with great intensity,” said Inter coach Simone Inzaghi.

Arsenal, on the other hand, experienced defeat for the first time in Europe this season and lie three points and seven places behind their opponents.

Arsenal manager Mikel Arteta said: “We were very harshly done by. There is no deflection, nothing you can do in the box, so can he get away from it?”

Barcelona also defeated Red Star Belgrade 5-2 in Serbia to claim sixth spot in the standings.

The Catalans took the lead on 13 minutes via a stooping header by defender Inigo Martinez.

But Red Star struck back just prior to the half-hour when Silas Mvumpa sprang the Barca offside trap and lifted the ball past Inaki Pena.
