His goals per game ratio was only bettered by Robert Lewandowski and Atalanta striker Luis Muriel in Europe's top five leagues.Wow, I could not have asked for a better way to start the season. 2021 Community Shield winners. 🙏🏽🏅Thank you to all the fans & my team mates who pushed us to the final whistle. @LCFC👏🏽🔵🦊#MakeJesusYourAim pic.twitter.com/WTjosxJcjk— Patson Daka (@PatsonDaka20) August 7, 2021Daka made his professional debut for Leicester City alongside new signings Ryan Bertrand and Boubakary Soumare in their Community Shield win over Manchester City.
