Kylian Mbappe has promised a reaction from PSG in their second Champions League match of the season.

The French champions face Istanbul Basaksehir on Tuesday, a week after losing to Manchester United in their opening group stage fixture.

"It's not the first time that we've lost the first match of the group stage. We know how to react," he told the club's official website.

"The matches succeed each other quickly and we'll try to win in Istanbul in order to honour the shirt and the club. All matches are important, but when you play every two or three days, it remains difficult, even if you are the biggest competitor."
