Radja Nainggolan's first European goal for his new club and a cool Mauro Icardi finish on the hour gave the Nerazurri their second comeback victory of the campaign, having dramatically beaten Tottenham 2-1 a fortnight ago.

No late fireworks were required on this occasion, although Inter were still made to work for their fifth straight victory in all competitions after falling behind to a Pablo Rosario stunner.

Nainggolan restored parity on the stroke of half-time before Icardi, one of the heroes of the Spurs success, took Luciano Spalletti's side level on points with leader Barca after two encouraging outings.

An entertaining first half promised goals from the outset and Rosario emphatically delivered in the 27th minute, whipping a sensational effort from right to left and past a flat-footed Samir Handanovic.

Two chances for Icardi suggested a response was forthcoming, although Inter received a let-off when the onrushing Handanovic escaped with a yellow card for handling the ball outside the area.

Mark van Bommel felt the goalkeeper's impeding of Steven Bergwijn deserved red and his mood was not helped a minute before the break, Nainggolan rifling in the equaliser from the edge of the area.

Gaston Pereiro curled a shot against the upright soon after the restart but, for all PSV's promise, it struggled to ever get to grips with Icardi.

The 25-year-old's 60th-minute winner owed as much to Jeroen Zoet's error as individual brilliance, the goalkeeper colliding with Daniel Schwaab and leaving Icardi to roll the ball into an empty net.

Handanovic was required to make one final save from an inventive Donyell Malen overhead kick 10 minutes from the end that maintained his team's perfect start in Group B.
