Excuse me aviii. Man U are not the most successful club in premiership history. Successful clubs are judge by the number of tiltle wins . Liverpool FC are the most successful with 18 titles and man U is second with 16 titles. Liverpool is better club than chelsea and Man u. Liverpool is the best brit club in europe. We have got more tournament victories than Man U and Chelsea in every prestegious tournament. I know AC milan is the BEST but we are best among the rest.
