Inter Milan won their fourth Champions League game in a row with a narrow victory over winless RB Leipzig.

The Nerazzurri took the lead in the 27th minute as Leipzig defender Castello Lukeba turned Federico Dimarco's free-kick into his own goal.

Captain Lautaro Martinez came close to prodding home a second but after a scramble inside the box Leipzig managed to clear.

Inter should have scored again with the first attack of the second half but Denzel Dumfries could only lift his effort over the top after his marauding run down the right.

Making his return to the starting XI, Hakan Calhanoglu tried his luck from range but Leipzig's Peter Gulacsi was equal to the powerful strike.

Dimarco's fine cross was met by the head of Marcus Thuram but the France international failed to direct his header on target from close range.

The German side piled on the pressure in the dying stages in the San Siro but could not find a way past a resolute Inter defence.

Inter have moved to the top of the Champions League table after picking up 13 points from a possible 15, while Leipzig sit 33rd.
