Kylian Mbappe's hat-trick powered Paris Saint Germain (PSG) to a 4-1 win over Barcelona in the first leg of their Champions League last-16 tie here on Wednesday.

Barcelona had the better of the early stages with Keylor Navas thwarting Antoine Griezmann before Lionel Messi opened the scoring in the 27th minute from the penalty spot after Frenkie de Jong was tripped by Layvin Kurzawa.
