Wasn't that our joint biggest Champs lge win.? Just checked, there were striking similarities to 4 years ago, 7:0 against a German team(Shalke), first goal a pen, that one was also even 3:0 at Half time.
Personally I think Chelsea would be a very decent draw for us.( we could then potentially knock them out of 3 cup comps in one season)However we dont want history to repeat itself too much as following the above game we lost to a team from London in the quarters didn't we!
Come to think of it we aren't great against other English teams in the CL though are we!
