MANCHESTER: Ilkay Gundogan scored twice as Manchester City sank Barcelona 3-1 in the Champions League on Tuesday to give manager Pep Guardiola an electrifying victory over his former club.
Barca had won 4-0 when the sides met two weeks ago, but although Lionel Messi put them ahead, City stormed back in thrilling fashion as Gundogan scored twice either side of a Kevin De Bruyne free-kick.
It ended Barcelona s run of five successive wins over City and moved Guardiola s side to within two points of Luis Enrique s Group C leaders with two games remaining.
After the doubts engendered by a recent six-game winless run, this was a resounding validation of Guardiola s principles, City outhustling his old team to give him the first statement win of his nascent tenure.
With Celtic holding Borussia Moenchengladbach in the other group game, City can secure a place in the last 16 if they draw in Germany on November 23, when Barca go to Celtic needing a point to progress.
Guardiola signalled his greater attacking intent by restoring Sergio Aguero to his starting XI, having left the Argentina striker on the bench for the reverse fixture two weeks ago.
The home side should have been awarded a penalty in the 11th minute after Raheem Sterling appeared to be tripped by Samuel Umtiti, but instead referee Viktor Kassai booked the England forward for diving.
Sterling was incensed and there was worse to come 10 minutes later as Barca took the lead in devastating style with a move that began with a block from Javier Mascherano inside his own area.
Messi, 15 yards outside the box, sprayed a pass wide to Neymar on the left and the Brazilian drove downfield before squaring to Messi, who neatly slotted the ball into the bottom-left corner.
Gundogan fired a shot down Marc-Andre ter Stegen s throat at the other end, but for a brief moment it looked like City were on the verge of being swamped as Neymar, Andre Gomes and Luis Suarez threatened.
City, though, refused to be deterred and their committed pressing game paid off in the 39th minute.
Sergi Roberto s overhit square pass from Barca s right was intercepted by Aguero, who played in Sterling, and he brilliantly rolled the ball across the box to give Germany midfielder Gundogan an easy tap-in.
City s tails were up and they almost went ahead two minutes later when Fernandinho s mishit shot eluded the lurking Aguero by inches.
The onslaught continued after the break, Sterling fluffing a chance with a heavy first touch and Aguero lashing wide, before Guardiola s men took the lead in the 51st minute.
Sergio Busquets s foul on David Silva presented City with a shooting opportunity 22 yards from goal and slightly to the left of centre.
De Bruyne administered the sentence, stroking the ball into the top-right corner past the wrong-footed Ter Stegen.
Now it was Barca who were rocking, De Bruyne s free-kick just eluding Nicolas Otamendi, Aguero heading Silva s cross wide and Aleksandar Kolarov narrowly failing to pick out the stretching De Bruyne.
Back came the visitors, Gomes rattling the bar after John Stones s overzealous tackle sent the ball into Suarez s path, but after De Bruyne had curled a shot a fraction wide, City struck again.
De Bruyne was the architect, his exquisite pass behind the full-back finding substitute Jesus Navas, whose cross struck Aguero and fell kindly for Gundogan to kill Barca off for good.
