Paris Saint-Germain (PSG) coach Unai Emery says his side have learned lessons from the past after they started their Champions League Group B campaign with a 5-0 thrashing of Celtic.

Neymar, Kylian Mbappe, Edinson Cavani's double and a Mikel Lustig own goal consigned Celtic to their record home European defeat and propelled PSG to the top of the table on goal difference from Bayern Munich, who they host on match day two.

It was a real statement of intent from this summer's big spenders who signed Brazilian Neymar and teenage sensation Mbappe in a bid to make a real impression on the competition.
