Pep Guardiola took a cheeky swipe at Manchester United as the Manchester City boss claimed his club's bitter rivals should name a stand after Omar Berrada if he revives their fortunes. Berrada quit his role as City's chief football operations officer last weekend to become United's chief executive. The appointment is a major coup for United as Berrada has played a significant role in City's dynastic success under Guardiola. City have won five of the last six Premier League titles and landed an iconic treble last season.
