I recently enjoyed watching home fixtures of Chelsea, Liverpool and Manchester United. Then I thought about the size of football pitch with those played in other European top tier leagues. The ones in English Premier League seem to be small when compared to the stadiums of clubs in Serie A, La-Liga and Ligue 1.
Does the size of the pitch remain the same everywhere? Also would lack of space in metropolitan areas could be a plausible reason why the pitches are small in Premier League or is there any other reason?
