Winners You can't call yourself a leading club in Europe without winning the Champions League. I don't know who the current top 10 teams are in Europe or how you could even quantify who is a top 10 team, but I dare say they have all won the Champions League except Chelsea and Arsenal (if the 2 latter teams even appear in the list).
The following link to Wiki shows all the winners of the Premier League or equivalent since its inception. Where are Chelsea on the list
