Had a few in the league cup to be fair.
Palace and Watford spring to mind, even Arsenal in 22 was fairly straight forward.
If your thinking about the Palace semi in 2001, even that wasn't straight forward, we went 2-0 down at Palace, got one back, but lost the first leg 2-1 [i remember Owen missing a few sitters in that leg], second leg we came out & blitzed Palace with 3 goals in 6 minutes early on, which made the the tie more comfortable than it was looking at kickoff, & ended up winning 5-0.
