Manchester United’s Champions League hopes were hanging by a thread after they lost 2-0 at home to Paris St Germain in their round-of-16, first leg match and had talisman Paul Pogba sent off late in the game on Tuesday.

Second half goals from Presnel Kimpembe and Kylian Mbappe gave the impressive French side a clear advantage ahead of the return in Paris on March 6 and Pogba’s dismissal for a second yellow card in the 89th minute makes the task even harder.

“We’re happy, but it’s only halftime,” said Mbappe. “In the last 20 minutes, we were hit by fatigue. We now have three weeks to make sure we’re ready to clinch our qualification.”

It was United’s first defeat under caretaker manager Ole Gunnar Solskjaer since he took over from the sacked Jose Mourinho in December and in many ways it was a reality check after 10 wins in 11 games domestically for the Norwegian.

Teenager Nicolo Zaniolo scored a quick-fire double to earn AS Roma a 2-1 win against Porto in their Champions League last-16 first leg on Tuesday.

The 19-year-old continued his superb breakthrough season by finding the net twice in six second-half minutes to become the youngest Italian to score two goals in a Champions League match.

Porto substitute Adrian Lopez, however, quickly responded with what could prove to be a crucial away goal.

The result ended a five-match winning run in Europe for Porto, who will welcome Roma to the Estadio do Dragao for the second leg on March 6.
