Rather sadly the Premier League now has a mandated standard pitch size, and there are only a few outliers remaining (basically older stadia where the architecture precludes conformance). So any new stadium has to conform to the standard dimensions, e.g. the new White Hart Lane (whereas the old White Hart Lane had a smallish pitch, which was often touted as conveying some advantage to Tottenham, especially most recently when playing an energetic pressing style under Pochettino)
