Well, not as you, but last 6 seasons i played same team in league and in champion league or/and cup. More or less both team are close in quality 3-8% diff. That turns on real rivality, first 2 seasons managed to get 1 tie in all games against it (think 10 or 12 games in total), costed me treble and cup , however, now having more luck or something, but our matches are 50-50, tbh, having real fun in those matches, manager is here, so more or less strategy and preparation are keys for wins on both sides
