Old habits kick in as Benzema-led Madrid comeback stuns PSG

"Real Madrid are still alive," said Karim Benzema, the 34-year-old striker who scored a second-half hat-trick as Paris Saint-Germain again self-destructed in the Champions League knockout stages.

PSG were cruising at 2-0 up on aggregate after Kylian Mbappe's 39th-minute strike.

For an hour, the Paris club looked assured of a last-eight berth, but Benzema turned the tie on its head with three goals in 17 minutes as Real swept to a 3-1 win and 3-2 aggregate triumph.

Even by PSG's standards, this was an epic collapse, five years to the day since Barcelona overturned a 4-0 last-16 first-leg deficit against them by winning 6-1 at Camp Nou.

Lionel Messi and Neymar were in Barcelona colours that day, but both were on the receiving end this time, unable to rid PSG of their habit of crumbling when it matters most.

In the year of the controversial World Cup in Qatar, Messi, Neymar and Kylian Mbappe were stitched together with limitless resources from the oil-rich Gulf state to win the Champions League, not crash out in the last 16.

Defeat throws Mauricio Pochettino's future as coach into serious doubt, raises further questions about Messi's departure from Barca and prolongs the Qatari-owned club's wait for that elusive European crown, despite more than a billion euros splurged on transfers.

Mbappe closer to leaving

"We have not managed our emotions well and we left ourselves too exposed," said Pochettino.

Mbappe took a step closer to leaving. The 23-year-old, out of contract in the summer, was at his scintillating best at his
