This is tough to answer the best "European team", because there is a difference between European, and...best English, Italian, Spanish,etc. I follow Liverpool, but not to be biased, Liverpool can make a great arguement that they are the best "European team". But...this does not mean that they are the best English team. That's without a question Chelsea.
When you compare Liverpool and Chelsea, a difference is seen: In the last three Premiership meetings between Liverpool and Chelsea, Chelsea has won all three, 1-0, 1-0, and 4-1. In the last three Champions League matches, Liverpool has won one and drawn two, 0-0, 1-0, 0-0. Clearly a difference in "English" and "European".
My opinion on best European clubs:
1. Liverpool
2. AC Milan
3. Juventus
4. Chelsea
5. Lyon
English:
1. Chelsea
2. Arsenal
3. Charlton
4. Manchester U.
5. Liverpool
Italian:
1. Juventus
2. Inter Milan
3. AC Milan
4. Sampdoria
5. Udinese
Spanish:
1. Real Madrid
2. Barcelona
3. Real Betis
4. Celta Vigo
5. Valencia
